Terms

  • assimilation
    • the "harmonizing" of sounds to make their articulation (speaking of) more efficient and pleasant
    • thus we have important and intentional, even though im- and in- mean the same thing -- their use is guided by the way our mouths form the sounds
  • cognate
    • = related sounds that yield shifts in pronunciation, generally between languages that have a common origin
    • ex. the English "night" is "cognate" with the German "nacht"
      • in English the "i" is cognate with the German "a"
      • and the ENglish "ght" is cognate with the German "act"
    • within a language, cognates are seen in words such as "night":
      • Old English: niht was changed to "night" in Middle English in order to represent the "ggh" sound of niht in Old English
        • eventually, the "ggh" sound was dropped and the "i" became "eye"-sound (from "ehh" sound)
        • but the spelling was kept the same, "night"
  • etymology
    • = word origin, or study of word origins
  • morpheme
    • = the smallest constituent of a word
    • some words are morphemes unto themselves ("it", "and")
    • others are a combination of morphemes ("itself", "below")
  • PIE
    • for proto-Indo-European language
    • = the origin or pre-origin language of Indo-European languages, which share the PIE language as their origin
    • Indo-European languages include, Celtic, English, French, German, Greek, Hindi, Latin, Persian, Spanish, and others across Europe and parts of central and western Asia and South Asia
  • root
  • suffix
    • = a word ending "inflection" (change in sound) that identifies or changes a root's part of speech

When is a prefix not a prefix?[edit | edit source]

  • many prefixes are attached to roots that are not words unto themselves
    • some scholars argue that these words are not "prefix + root" and stand as single "morphemes" (word units)

Letter sound shifts[edit | edit source]

  • because of the way letter sounds are formed by the mouth (physically)
    • some letters more naturally precede others
    • this process is called "assimilation" or "linguistic economy"
    • see Euphony
  • examples:
    • "m" starts with closed lips, then open lips ("mmmah" sound)
    • "n" starts and ends with open lips, along with release of the tongue from against the front teeth ("nnnah" sound)
    • "p" starts with closed lips, then open lips > open lips ("pppuh" sound)
    • thus
      • n + p requires open for n, then close and open for m
      • whereas m + p only requires closed lips for m, which transitions easily to the open lips p sound
  • consequently, some prefixes with the same meaning use different letters, depending on the first letter of the root word
Pronoun ending letter
-b, -m, -p -c, -d, -f, -g, -h, -j, -l, n, -r, -q, -t, -v
m & n em-, im-ember, eminent, empathy, immaterial, important en-, in-include, induce, infuse, ingress, inhuman, injury, enliven, enrage, inquisitive, into, invisible
m & n um-umbrella, umpire un-unclear, under, unfettered, unhinged, unjust, unlimited, unrest, unready, invertibrate
a & ad a-

abstract, amaze, apparent

ad-addition, adhere, advertize
com & con compete context

Prefixes with dual, opposite meanings[edit | edit source]

  • some prefixes have opposite meanings
    • adhere = stuck to
      • ad from a- (adding the "d" before the h
        • ad- (to, into) + haesitare (stuck, in place)
          • "here" = from PIE root *ghais- forms adhere, hesitate
      • versus
    • averse = against, disliking, hostile, unwilling
      • a- (against, not) + verse (turn)
        • = turn against
