step 2: suffix 后綴
構詞法包括合成、派生、轉化和縮寫簡寫。詞綴是派生的一部分。
the basic part of any word is the root; to it, you can add a prefix at the beginning and/or a suffix at the end to change the meaning. for example, in the word “unflattering,” the root is simply “flatter,” while the prefix “un-” makes the word negative, and the suffix “-ing” changes 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 come 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” = “suffix”
note that both the “-d” of “ad” and the “-b” of “sub” change the last letter.
here are some of the most common 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 independent prefixes and suffixes.)
