  • DC = "dependent clause"
  • SV = "subject + verb"
  • SVO = "subject + verb + object"
  • DO = "direct object"
  • IO = "indirect object"

Adjective

modify nouns

• nouns = things
• adjectives add additional information to "qualify" or "modify" the noun in order to create a more specific meaning, ex.:
  • "I wore the shoes" v. "I wore the comfortable shoes"
    • the idea changes from "I wore shoes" (in general) to the kind of shoes I wore, i.e, "the comfortable ones"

remain singular

• adjectives do not change to match plural nouns
  • i.e. "the red shoe" >> "the red shoes" and not "the reds shoes"
    • whether or not "shoe" is singular or plural, the adjective remains the same
      • other languages require singular/plural matching, such as "la chaussure rouge" ("the red shoe) v. "las chaussures rouges" (the reds shoes)

general uses of adjectives

• adjectives clarify what kind, what characteristic, what size, which details", etc.
  • what kind: "the regular class"
  • what characteristic: "the difficult class"
  • what size: "the small class"
  • which details: "the rowdy class"
  • note:
    • numbers are not technically adjectives, although they can operate like them
      • "the third class" = a qualification of which class (among others)

nouns and verbs as adjectives

• when a noun or an adverb modify a noun, they are acting like adjectives
  • see "Noun as modifier (attributive)" below
    • ex.: "dog food" = "dog" describes the kind of food, even though "dog" is a noun"
  • see "past participle" under Verbs
    • ex.: "cooked food" = "cooked" describes the kind of food, even though "cook" is a verb

adjectives following subject-verb

• sometimes adjectives stand alone following a verb
  • ex. "Josephus felt sad"
  • here the adjective "sad" is modifying the subject (noun) "Josephus"
  • the adjective is not modifying the verb "felt"
    • if it were, it would an adverb, as in "Josephus felt badly for the hurt boy"
      • "badly" = adverb that modifies the verb "felt
  • verbs that may be followed by an adjective (and not an object/noun) include:
    • be, feel, taste, smell, sound, sound, look, appear, seem
• these sentences, therefore do not have objects (nouns)
  • instead, they have a "subject complement" since the adjective "complements" the subject (a noun)
  • note that "I feel sad", "sad" is not describing the action "to feel", it is describing the subject "I"

postpositive adjectives: adjectives that follow nouns

• postpositive adjectives are uncommon but have a couple general uses:
• modifying "indefinite pronouns"
  • "someone interesting" or "something great" = the adjective follows the indefinite pronoun
  • indefinite pronouns refer to "some" -one, -body or -thing and not to a definite, or specific person or thing (this, that, they, him, you, etc.)
• postpositive adjective phrases for emphasis or comparison:
  • "The team needs a player better than that"
    • the adjective "better" describes the noun "player" but follows the noun instead of preceding
  • "A dog this big"

• compound* words in which the noun follows the adjective:
  • "attorney general"
    • "general is an adjective meaning "main" or "principle" (and not the noun meaning military commander)
    • thereby, to pluralize the compound word, the noun is plural but the adjective is not:
      • "attorneys general"
        • *note that "compound words" can be either "open", as in "boy scout" or full moon" or closed, as in "bullfrog" or "mailbox" or hyphenated, as in "long-term" or "on-campus"

Adverb

modify verbs

• adverbs provide additional information about an action (verbs), including:
  • how, when, where, degree, or state of an action
  • ex. "He shopped quickly"

modify adjectives

• adverbs can also modify adjectives:
  • in the sense of describing "the state", degree, or situation of the descriptor
  • ex. "the coach was extremely angry"
    • "extremely" describes the extent to which the coach was "angry" (an adjective)
    • therefore, the adverb "extremely" acts upon the adjective "angry" as opposed to the verb "was"

adverbs to describe how

• adverbs can answer the "how" of an action (or verb):
  • how: "Soraya studied hard" or "Soraya studied quietly"
    • note that "hard" is also an adjective that describes high density of an object: "the stone is hard"
    • but here it is used to modify the verb in that she studied "strenuously"
• adverbs never describe a noun
  • ex. "she called the broken phone stupid" = the phone is stupid,
    • v. "she stupidly called the broken phone" = she mistakenly called a broken phone
• Sources:
  • Adverb (literarydevices.net)
  • Adjective or Adverb (OWL)

adverbs to describe when

• are used to express the "when" of an action (verb)
  • ex. "Jocelyn arrived early"
    • note the -ly form of the word "early," which indicates it is an adverb
    • however, if we say, "Jocelyn arrived late", "late" is an adverb the same as "early"
• "adverbs of time":
  • yesterday, today, "tomorrow
  • these are adverbs because they modify the verb as to when the action occurred
    • note that these words can also be used as nouns
      • see the entry for "Yesterday" on [Word Parts of Speech & Their Rules Y-Z]

transitional adverb

• = connect actions and ideas
• or move a sentence or sentences from one idea to another
  • thus is a conjunction, technically, "conjunctive adverb"
    • however, they do not combine independent clauses
      • i.e., are not equivalent to "but" or any of the seven "coordinating conjunctions" (FANBOYS)
• transitional adverbs include consequently, furthermore, however, meanwhile, moreover, nevertheless therefore and thus
  • are similar to other "transition words" or "transition phrases" that act as conunctions
• when used in the middle of a sentence, the transitional adverb is parenthetical
  • ex. "I was hungry, late, and, moreover, broke" (yikes!)
• sources:

  • Correct Use of However, Therefore, Moreover (perfectyourenglish.com)

• Sources:
  • Is "yesterday" a noun, an adjective or an adverb? (stackexchange.com)
  • this source argumes that "yesterday, today" etc. are nouns: Are ‘Yesterday,’ ‘Today’, and ‘Tomorrow’ Nouns or Adverbs? (parentingpatch.com

Article

• indicates a specific or general reference to a noun
  • articles are sometimes listed under the category of "determiner"
• two types of articles:

definite article (the)

• "the"
  • refers to a specific noun, usually already stated or defined

indefinite article (a & an)

• "a" or "an"
  • refers to a general noun, usually one not already stated or defined
  • note: indefinite articles are not used to refer to a general noun or one that cannot be counted
    • ex. "a water" is incorrect
    • see "count" and "noncount" nouns usage

a v. an

Rules for Articles Use w/ Count & Noncount Nouns, Abstract/Generic Nouns, & Nouns with Superlatives

ARTICLE RULE	COUNT NOUNS	NONCOUNT NOUNS
Introducing a noun or unknown Noun	Takes the indefinite article (a, an) "A man I met the other day" = who is "man" is not yet known so the indefinite article is used to express that introduction/ unspecific reference	If unknown = no article
Referring to an already known noun	Takes the definite article (the) "The man I told you about earlier"	Takes the definite article (the) "The water in the lake is warm!"
Referring to a generic category	No article "I love pickles" i.e., "pickles" can be counted but is used here as a category or type of food	no article "Water is good for you"
Abstract noun (figurative, not literal) or an adjective used as a noun to describe a general idea or condition	Definite article (the) "The ghost in the machine" "The decency in her actions"	No article "Ambition can be dangerous" "Friendship is wonderful"
Nouns with Superlative adjectives superlatives express the highest degree therefore superlatives create a singular noun	Definite article (the) "the best coffee", "the highest mountain"	Superlatives always modify singular nouns i.e, "the best" = one not multiple things
Different uses of count, non-count, etc. nouns some nouns can be expressed in all these categories thereby the use or non-use of an article shapes its meaning	"coffee" for example: "The coffee is strong!" (a specific coffee) "I like strong coffee" (coffee in general) "I like a coffee that is strong" (a kind of coffee that I like)

• a = for use before consonants (hard sounds)
  • "a cow"
  • also used before "u" when the "u" makes a "y" sound
    • "a usable" (a "yoos-able") "a union" (a "yoon-yun") or "a unified" (a "yoo-ni-fied")
      • v. or "an ugly" or "an unsatisfactory"
  • or before "o" when the "o" makes a "w" sound
    • "a one-time" or "a
• an = for use before words that begin with a vowel or a soft "h":
  • "an owl", "an hour"
  • hard "h" sounds use "a":
    • "a horse", "a historical"

indefinite articles & count, noncount & generic nouns

• if the noun cannot be counted, then it does not take an indefinite article
  • ex.
    • "rain" cannot be counted, so "a rain" is incorrect
      • as opposed to "a rainfall" which can be counted
    • "water" cannot be counted, so "a water" is incorrect
    • however, if referring to "a water" as in "a glass" or "a bottle" of water, which CAN be counted
      • therefore the indefinite article "a" works, as in "may I have a water?"
• generic categories do not take the indefinite article:
  • when the noun represents a generic or general idea or category, the article is omitted
  • ex. "They went on vacation" as opposed to "they went on a vacation"
  • "The mentor gave him good advice" as opposed to "gave him a good advice"
• for more on Articles see:
  • Purdue OWL on using articles
  • What Are Articles?
  • DEFINITE AND INDEFINITE ARTICLES (Butte.edu)

Conjunction

• connect or coordinate ideas, sentences, or thoughts

other types of conjunctions

  • types of conjunctions (wordagents.com)
  • Conjunctions and Coordination (owl.purdue)
  • Conjunctions (englishgrammar.org)

Determiner

• introduces a noun or indicates an amount, specificity, or generality of a noun
  • determiners are traditionally considered adjectives, as they modify nouns
  • however, here we are considering "determiner" as a unique category
    • but also "article" as a unique category unto itself, even though it is considered a type of determiner
• determiner categories:

demonstrative

• this, that, these, those
  • note that "which" and "that" are pronouns that may act like a determiner ("that car which goes faster")

numeral

• zero, one, two, three... (numbers)
• first, single, once, dozen
  • note that numerals are distinct from quantifiers

quantifier

• a few, a little, all, another, any, both, each, enough, every, few, half, many, more, none, several, some, such
  • enough= indicates "sufficiency"
  • a few, some, more, etc = indicate "degree"

possessive

• hers, his, my, our, theirs, whose, your
  • note that these possessive indicators are actually pronouns, but they are considered "determiners" in that they are used to specify ownership of something\

See for more on determiners:

• Determiner- Explanation and Examples (partofspeech.org)

Interjection

• aside remarks or interruptions
• an exclamation
  • expresses a spontaneous reaction or emotion
• click EXPAND to see examples of interjections:

• "no!"
• "okay"
• "damn!"
• "heh!"

Noun

• persons, places, things
• proper nouns

subject

• subjects of a sentence are always nouns
• the subject is the person, place or thing that does the action (which is expressed by a verb)
• note: the word "subjective" means "from one's point of view," thus, like the subject of a sentence, subject is doing the action
  • (i.e., from the "subjective point of view

object

• note: the word "objective" means "from a general point of view," thus, like the object of a sentence the object is not the actor
  • (i.e., from the "objective point of view")
• direct object
  • = the object that is the "direct" recipient of the action (verb)
    • ex. "I ate the donut"
• indirect object
  • = the object that is an "indirect" recipient of the action (verb)
    • ex. "I gave the donut to the boy"
      • the verb gave requires the direct object "the donut"
      • but it also has a recipient of the action, thus "to the boy"

multiple subjects, verbs & objects

• sentences may have multiple subjects, verbs and objects
• ex. "The man, his son and his daughter looked around, compared, and bought new shoes, shirts and hats."
  • secondary verbs may follow the objects of prior verbs, as in:
    • ""The man, his son and his daughter looked around the isles, compared prices, and bought new shoes, shirts and hats."

consecutive nouns

• nouns can be next to one another in a sentence
• if so, they may represent either:
  • indirect + direct objects ("She told her father the truth")
  • appositive nouns (the first noun acting as an adjective: "dog food")
  • a list of nouns, however, these will be separated by commas ("dogs, cats, and horses")
  • possessive nouns (one noun possesses another: "the dog's bone" or "his book")

consecutive nouns as direct and indirect objects

• consecutive nouns can act as multiple objects of a verb
  • i.e., two nouns next to one another
  • as in "I gave the boy a donut"
• when the action has a direct and indirect object, the indirect object is often preceded by "to" in order to indicate the direct object
  • however, we frequently drop the "to", which remains implied in the sentence
    • so instead of "I gave a donut to the boy" we simply say, "I gave the boy a donut"
  • another ex. "She gave the man grief"
    • can also be expressed as "She gave grief to the man"
    • the noun "grief" is what was given (direct object) and the noun "man" is to whom the grief was given (indirect object)

Click expand for an example of multiple nouns as objects from CB Writing practice test 10, question 36:

Tuition-reimbursement programs signal that employers offer their [36] [workers’ opportunities] for personal and professional development.

A) worker's opportunities [NO CHANGE]
B) workers opportunities’
C) workers opportunities
D) worker’s opportunity’s

• elimination
  • x A) the possessive "worker's" confuses the direct object "opportunities" with the indirect object "workers"; in other words, "employers" don't offer "workers" they offer "opportunities"
  • x B) and x D) the noun "opportunities" cannot possess the preposition "for"
• Correct answer C) = SUBJECT: employers VERB: offer INDIRECT OBJECT: workers DIRECT OBJECT: opportunities

consecutive noun as modifier (appositive)

• one type of consecutive nouns may be a noun acting as a modifier, as if an adjective (but not one)
• such nouns are called "attributive" nouns
  • also called "adjunct" (supporting of) nouns or "apposite" (related to)
• attributive nouns modify or qualify another noun
  • modify = change or add to the meaning of
  • qualify = limit the meaning of
  • attributive = provides an "attribute" or characteristic or quality to the other noun
• ex.: "dog food"
  • i.e.: "dog food" = "a type of food that is for dogs"
  • "dog" thereby indicates an attribute, or type or characteristic, of "food"
• example of multiple objects + a attributive nouns:
  • "The pitcher threw the batter a hardball pitch"
  • S: pitcher V: threw IO: catcher ADJ: hardball (appositive noun) DO: pitch
    • could also be expressed as: "the pitcher threw a (hardball) pitch to the catcher"
      • "hardball" = a noun, but here it is describing the direct object "pitch"
      • thus "hardball" is acting like an adjective
• the attributive noun is (almost) always singular
  • = because it is acting like an adjective, which always remains in the singular form ("red shoes" as opposed to "reds shoes")
  • = as a category or type, the noun must remain singular
  • exception for plural attributive nouns = special words such as "arms race" or "rewards card"
  • possessive attributive noun:
    • ex.: "the National's game"
    • these are often morphed into plural attributive, thus "National's game" becomes "Nationals game", "reward's card" becomes "rewards card", or "lady's night" becomes "ladies night"
  • multiple attributives
    • ex.: "beef dog food" or "
    • news headlines often use multiple attributives, such as "South Park man Kenneth "Kenny" McCormick dies again"
• strict grammatical terms does now apply the "attributive" label for "adjective homograph" nouns (such as "iron" or "paper") or "compounds" or "open compounds"
  • see https://www.merriam-webster.com/help/explanatory-notes/dict-attributive-nouns
• attributive nouns are not adjectives
  • the only syntactic form of an adjective that the attributive noun employs is the "prepositive" position
    • i.e., preceding the noun it modifies
      • big dog, small house
  • attributive nouns cannot operate as post-positive adjectives (following the noun):
    • whereas an adjective can be a subject complement:
      • boring meeting >> the meeting is boring
    • dog food >> food dog or business meeting >> meeting business << don't work
  • attributive nouns cannot operate as subject complements (as do adjectives)
    • the food is dog or the meeting is business << don't work
  • attributive nouns cannot take on a comparative form (as do adjectives)
    • whereas nouns can go from big to bigger
      • big test >> bigger test
    • attributive nouns cannot: businesser meeting << doesn't work
• see also additional entry on
  • "appositive phrase"
  • compound noun
  • noun adjunct
• see:
  • Noun adjunct (wiki)
  • Nouns as Modifiers (meg.com)

possessive nouns

• nouns may possess (or own) one another
  • ex. "Jake's house"
  • possession is indicated by the "apostrophe"
    • other languages express it as "the house of Jake"
    • English indicates the "genitive" case, which in Latin marks possession\
  • singular v. plural possession
• to indicate possession:
  • singular nouns add 's (apostrophe + s) << "the horse's saddle"
  • plural nouns add s' (s + apostrophe) << "the horses' field"
  • if a singular noun already ends with an s, possession is indicated by adding either an apostrophe + s ('s) or just the apostrophe (')
    • ex. "Jesus's sermon"
    • or "Jesus' sermon"
      • either form is correct
  • see https://www.grammarbook.com/blog/apostrophes/apostrophes-with-words-ending-in-s/
• possessions v. contractions ending in -s
  • pronoun contraction using apostrophes + s
    • it's = the contraction for "it is"
    • he's or she's = contractions for "he is" and "she is"
      • the possession forms are "his" and "hers"
    • "who's" = "who is"
      • the possessive form = "whose"
    • other contractions such as that's, when's, how's, etc. express possession with the verb "have," as in "that has", "when has" or "how has"
• to do: add about other apostrophe uses, such as '49, 'nuff said

plurality, count distinction & generality

• plurality = noun shifts from singuar to plural, usually marked by the suffix "-s"
  • i.e., a dog, two dogs
• "count distinction" is sometimes called "the grammar of counting"
• regards singular v. plural nouns and distinctions between plural nouns of things than can be individually counted or not
  • generally marked by the suffix "s" for plural
• "count distinction" and determiners
  • generally the "count distinction" is between objects and substances
    • objects can be counted and differentiated (one of that object can be isolated from another of that object group)
    • substances that have no set distinction and therefore cannot be counted
  • plural nouns that can be counted use the determiner "many"
    • as in "many people" << the number of people can be counted
    • plural nouns that can NOT be counted use the determiner "much"
      • as in "much water" << one cannot count "water", although "much" indicates a large amount of water

Preposition

• creates a prepositional phrase, which:
  • express relationship in time, place, or sequence
  • adds information to a sentence
  • relate to other word forms to one another, including nouns (usually), adjectives, and verbs
• list of prepositions:

about, above, according to, across, after, against, along, among, around, at, before, behind, below, beneath, beside, between, by, down, during, except, for, from, in, in front of, inside, instead of, into, like, near, of, off, on, onto, out of, outside, over, past, since, through, to, toward, under, underneath, until, up, upon, with, within, without

Overlap of prepositions, adverbs & subordinating conjunctions

• some words operate or "overlap" in their grammatical roles

click EXPAND for more on the overlap of prepositions & adverbs and prepositions & subordinating conjunctions

• overlap of prepositions and adverbs:
  • = "intransitive preposition"
  • = prepositions may or may not define a "noun phrase" (which prepositions would normally accompany)
    • note:
      • transitive verb = must be accompanied by an object
      • intransitive verb = does not need an object ("I feel happy")
      • so intransitive prepositions do not need a noun or noun phrase
• most dictionaries qualify intransitive prepositions as adverbs, such as "abroad," "now," "until"
  • ex. of intransitive preposition: "They went ahead" or "The dog is outside"
    • with a noun these would be more clearly prepositions: "They went ahead of the others" or "The dog is outside the fence"
• overlap of prepositions and subordinating conjunctions
  • = a "conjunctive preposition"
  • ex.: "I got my license before last year" (before= preposition that defines when "I went to school")
  • vs.: "I got my license before last year ended" (before = combines "I got my license" and "last year ended" and defines which came first)
    • we can view "before" as subordinating the phrase, "last year ended," which is technically a complete thought and sentence
    • however, since "before" is defining the "when," which is a core function of a preposition, we can call it one, or call it a "conjunctive preposition" when also acting as a #subordinating conjunction.
  • ex.: "She paid the bill after dinner"
  • vs.: "She paid the bill after she ate dinner"
  • ex.: "He played like a pro"
  • vs.: "He played like he was a pro"

prepositional phrase

• = a phrase created by a preposition + its object
• = dependent clauses, so are separated from a main or dominant clause by a comma
• prepositional phrases that modify verbs are called ""adverbial phrases"
• see
  • [Prepositional phrases: what they are and examples (writer.com)]

other exceptions

• prepositional phrases can also act as nouns, usually as the subject of a sentence
  • and usually in reference to a location or time that has an action (verb), such as:
    • "During the summer is the best time to play outside"
    • "After I exercise is when I feel best"
• see:
  • [Prepositional Phrases as Nouns(englishgrammar.com)]
  • [How to Use Prepositions as Subjects, Subject Complements, and Direct Objects (brighthub.com)]

Pronoun

• "pro" = for; "noun"
• refer to a noun in oder to avoid repetition
• pronoun forms
  • subject
  • object
  • possessive
  • comparisons
  • see How to Pick Pronouns for Comparisons (Dummies)

prepositions in comparisons

• "She is better at it than me" vs "She is better at it than I"?
  • both work:
    • "than I' = "She is better than I am" << = "than" is a conjunction
    • "than me" = She is better at it than me" < = "than" is a preposition
• see List of word parts of speech & their grammar rules - School4Schools.com Teacher Lesson Planner & Student Study Guide

Verb

• express action or a state of being (a condition)
• verb forms:
  • verbs, or an action of a subject, can be expressed by a single verb or by a phrase, or multiple words, that expresses an action
  • verb phrases are known as "predicates"
  • technically = "predicate"
    • predicate = "the portion of a sentence which makes a claim about the subject" Predicate (grammar) (wikipedia)

verb "moods"

• "grammatical moods" = a feature of verbs whereby the speaker "inflects" or expresses an idea by modifying tone and emphasis for a specific meaning
• there are four general grammatical moods for verbs:

indicative mood

• a statement of fact
• often in the form of a "declarative" sentence
  • ex. "I am hungry!"
    • the speaker emphasizes "I" and "am"

imperative mood

• a command or advice
  • ex. "You should really get to work"
  • the speaker will emphasize the adverb and object

subjunctive mood

• expresses emotion, possibility or opinion
  • possibility = something that has not happened"
  • ex. "Once we get this done..."

optative mood

• expresses a wish or hope for something
  • ex. "May the best man win!"
  • the speaker's inflection frequently rises with the last word
  • may often also be subjunctive
• see https://en.wikipedia.org/wiki/Proto-Indo-European_language#Morphology

transitive and intransitive verbs

• indicates if an action (verb) is expressed with or without a direct object
  • transitive verbs or transitive verb forms act upon a direct object:
    • ex. "The soccer player kicked the ball hard"
  • intransitive verbs or intransitive verb forms do not have a direct object
    • ex. "The soccer player played hard" (a direct object is not required for the sentence to make sense
    • intransitive verbs cannot be used in the passive voice
      • ex., "The dog barked" is a complete sentence and "barked" does not require a direct object
      • however, we cannot say, "the dog was barked"
• why does transitive/intransitive verb usage matter?
  • a common error is to attach a preposition to a transitive verb:
    • since they have direct objects, a transitive verb cannot be separated from its object, ex.:
      • incorrect: "That professor teaches about Biology"
      • correct: "That professor teaches Biology" (the direct object is not separated from the verb)
      • other incorrect examples:
        • "She told about her trip." v. "She told us about her trip."
        • "His dad bought

infinitives

• infinitives use "to"
  • ex. "I go to see the game"
• root forms act like infinitives but without the "to"
  • infinitive and base forms are generally interchangeable:
  • ex. "He helped her clean her desk" (root form)
  • v. "He helped her to clean her desk" (infinitive form)
• note that "root" and "base" forms are used interchangeably
  • except "base form" of a verb includes infinitive and simple present forms of the verb

present tense forms

• simple present
  • denotes a single action that is repeated, always happens, or the present condition of something
  • examples
    • repeated action: "I eat lunch at noon."
    • action that always (or, in the negative, never) happens: "I can't speak Latin"
  • denotes the condition or state of something: "The car is clean" or "I feel great!"
  • simple present form is also considered as a "base" verb form
• present progressive
  • = -ing form for a verb to express an ongoing action
    • used with "to be" conjugations ("am" "is", etc.) the -ing verb form denotes an ongoing action
    • ex. "She is dancing"
    • see participle for the -ing form of a verb that acts as an adjective or a noun (called a gerund)
  • note that present progressive verb forms are frequently used to combine sentences or independent clauses
  • click EXPAND to see examples of present progressive verbs used to combine independent clauses

• ex. "I went to see the sequel, and I hoped it would be as good as the first
• the two independent clauses (complete sentences) can be combined by converting the "I hoped" to the present progressive form, "hoping"
• "I went to see the sequel, hoping it would as good as the first"
• note that "hoping" renders the second clause dependent (not a complete sentence or thought), thus employing only a comma and not a comma + conjunction
• present progressive verbs subordinate clauses:
  • "Hoping it would be as good as the first" is not a complete sentence or thought
    • thus it is a dependent or subordinate clause

participles and gerunds

• verb forms that act like an adjective, adverb or noun
• types:
• participles
  • present participle
    • verb form using -ing that acts as an adjective or an adverb
  • past participle:
    • past tense verb form that acts as an adjective
  • gerund
    • verb form using -ing that acts as a noun

present participle

• uses the -ing form of a verb as an adjective or an adverb
  • present participles describe nouns, noun phrases, or verbs (actions)
• present participles as adjectives:
  • "The boiling water is hot" (describes the water)
  • "This trip is exciting" (modifies or describes the trip)
  • "The directions are confusing" (modifies the directions)
• present participles as adverbs:
  • note: here grammar becomes debatable: this form of a particle can be seen as an adverb or a gerund (noun):
  • Smiling, she went about her work" (modifies how she "went about her work")
  • or "She went about her work smiling"

participles and adverbs

• present participles may themselves be modified by an adverb
  • ex.: ** or "She went about her work smiling enormously"

past participle

• verbs in the past tense used as an adjective
  • = the simple past tense of a verb is used to show a condition of something
  • typically are -ed -en and -t forms
  • includes irregular verbs in the past tense, such as "to be" "to go" etc.
• ex:
  • "Boiled water is sanitized" ("boiled" and "sanitized" describe the noun, water)
  • "The glass was broken when I found it" ("was broken" describes the noun, glass)
  • "The cut flowers are pretty" ("cut modifies the noun, flowers)

gerunds

• • verbs that act as nouns
  • use the -ing form of the verb
• ex:
  • "to swim" + -ing = "swimming" = a noun for the act of swimming
  • "Swimming is fun"
  • "Boiling the water sanitizes it" ("boiling" is an act, therefore a noun, from the verb "to boil")
• gerunds are used as objects of verbs, ex:
  • "The student hesitated raising her hand"
• Note: gerunds are often interchangeable with infinitives
  • "The student hesitated raising her hand" vs "The student hesitated to raise her hand", or:
  • "I hate doing math" vs "I hate to do math"
  • however, note that gerunds and infinitives may act differently in terms of the object of the sentence:
• gerunds are used with prepositions, ex:
  • "Before leaving, he turned off the lights" << "before" is a preposition
  • "Joanna stepped carefully after dropping the glass" <<"after" = preposition
• click on EXPAND for how gerunds and infinitives change the meaning of a sentence using College Board Writing practice test 6 question 21:

"Burland advocated using soil extraction:"

• A) NO CHANGE
  • "Burland advocated using..." = he advocates for the use of soil extraction (he advocates the the object)
• B) advocated to use
  • "Burland advocated to use..." = he advocates "to use" (he advocates the action)
• A) NO CHANGE is correct because it is the object of the sentence, "soil extraction," that Burland advocates, not the action of its use (to use")

telling the difference between a gerund & a participle

• since participles act as adjectives, they are not essential to make a complete sentence or thought
• since gerunds act as nouns, they are essential to make a complete sentence or thought (as a subject or object or other noun form)
• to test whether verb is acting as a gerund or participle:
  • is it modifying a
  • remove it from the sentence

using gerunds and participles

• the reason we use gerunds and participle is to express either the state of an action ("swimming") or what an action does/did to a noun ("boiled water")
• gerunds and participles allow for simpler expression of those ideas than if they were expressed as subject-verbs
• gerunds may act as subordinating conjunction
  • such as "Scrambling up the hill, he barely made it to the top."
    • "Scrambling up the hill" is not a complete thought or sentence, so it is subordinate to the main clause, "he barely made it to the top.
  • as opposed to "He scrambled up the hill, and he barely made it to the top"
  • or "He scrambled up the hill and barely made it to the top"
    • each form expresses a different emphasis upon sentence parts
• -ing forms as adverbs may concisely express a "relative clause" (a sentence part that is related to

participles as dangling modifiers

• participial phrases are often the source of "dangling modifiers"
  • = adjectives or adjective phrases that are not clear as to what they modify, ex:
    • "Smiling happily, she won the choral competition"

= unclear if she won the competition becuase she was "smiling happily" or she was "smiling happily" when she won the tournament

Sometimes, it can be difficult to tell the difference between a gerund and a participle. A good rule of thumb to follow is that a participle can be omitted and the sentence will still make sense.

The old lady showed me the way to the museum still works without the participle "smiling," but the same doesn't work for a gerund. If you omit “smoking” from the sentence, He was scolded for smoking, it won’t make sense.

The sentence, Visiting relatives can be boring, is ambiguous because visiting can be interpreted here as a gerund or as a participle. If you interpreted it as "going to relatives houses can be boring," you saw it as a gerund that appears in the subject position in the sentence. You can replace it with a simple noun to confirm it (e.g. Math can be boring). If you interpreted it as "relatives who come to your house can be boring," you saw it as a participle that serves as an adjective modifying the noun "relatives." In this case, you can omit it (Relatives can be boring) and the sentence will still make sense.

subjunctive

• also called "subjunctive mood"
• expresses a hypothetical or possible scenario
  • called "mood" because it often expresses an emotion or desire for something to happen or exist
• subjunctive phrases usually pair verbs of opposing tenses, as in "if I had, I would"
  • ex.: "If I had studied harder, I would have done better on the test."
    • "had studied" = past perfect (an action that happened at one time)
    • "would have studied" = conditional perfect tense (also "past tense modal")
      • "would" = past tense of "will" thereby represents an imaginary action from the past

  • [English subjunctive(wiki)]

verb conjugations

• students of Latin, Spanish or French verb conjugations while not learning about them in English
• English has conjugations, as do other Indo-European languages
  • however, the conjugations in English do not vary as much
• conjugations work by changing the verb suffix or form to match subject case
