Prefix definitions, etymology & examples

Terms

• assimilation
• 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?

• 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

• because of the way letter sounds are formed by the mouth (physically)
  • some letters more naturally precede others
• 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
