For example, in the word “un flattering,” the root is simply “flatter,” while the prefix “un ” makes the word negative, and the suffix “ ing” chan ges it from a verb into an adjective (specifically, a participle). English itself does not use prefixes as heavily as it once did, but many English words e from Latin, which uses prefixes and suffixes (you can use the word affix to refer either to a prefix or a suffix) quite extensively. For example, the words “prefix,” “suffix,” and “affix” themselves are all formed from “fix” by the use of prefixes: “ad” (to) + “fix” (attached) = “affix” “pre” (before) + “fix” = “prefix” “sub” (under) + “fix” = “suff ix” Note that both the “ d” of “ad” and the “ b” of “sub” change the last letter. Here are some of the most mon Latin prefixes (for the meanings of the Latin roots, look up the words in a good dictionary): ab (away) abrupt, absent, absolve ad (to) adverb, advertisement, afflict in (not) incapable, indecisive, intolerable inter (between, among) intercept, interdependent, interprovincial intra (within) intramural, intrapersonal, intraprovincial pre (before) prefabricate, preface prefer post (after) postpone, postscript, postwar sub (under) submarine, subscription, suspect trans (across) transfer, transit, translate Affixes Morphemes added to free forms to make other free forms are called affixes. There are three principle kinds of affixes: 1. prefixes (at beginning) — “un ” in “unable” 2. suffixes (at end) — “ ed” in “walked” 3. circumfixes (at both ends) — “en — en” in “enlighten” (These always seem to consist of otherwise attested indep
