Participle phrase & infinitive phrase

Terminology

• clause
  • a part of a sentence that contains a finite verb (a verb that has a subject)
• complement
  • a word, phrase, or dependent clause that adds information to a subject or verb (as part of the predicate)
• finite verb
  • a verb that has a subject
  • it is "finite" because it is "bound to" or associated with a subject
• infinitive
  • the "to" form of a verb
    • ex. to be, to play, to believe
    • infinitives can act as a noun, adjective, or adverb
• non-finitive verb
  • a verb that does not have a subject
  • and it therefore does not act as a verb, and instead acts as a noun (called "gerund"), adjective, or adverb
    • non-finite verbs are either participles or infinitives
      • (note: not all participles are non-finite)
• object
  • a noun or noun phrase that is the recipient of a verb or preposition
    • ex.
      • She kicked the ball ("ball" = object or "kicked")
      • He ran to school ("to school" = prepositional phrase complement of the verb "ran")
• participle
  • the -ing or -ed form of a verb
• phrase
  • two or more words that do not have a finite verb
  • participle phrases and infinitive phrases are formed by the non-finite forms of verbs as either participles or infinitives
