? Affixation is generally defined as the formation of words by adding word-forming or derivational affixes to bases . This process is also known as derivation ,by which new words are derived from old or base forms . The words created in this way are called derivations . According to the positions affixes occupy in words , affixation falls into two subcategories: prefixation and suffixation

Prefixation is the formation of new by adding prefixes to bases . Prefixes do not generally change the word-class of the base but only modify its meaning . For convenience of study, we shall present prefixes on a semantic basis, that is , we shall group prefixes into semantic sets , each consisting of all the major prefixes that have similar meaning and functions . At same time , for ease of access, the affixes in each set are arranged in alphabetical order.

? 1.1.1negative prefixes ? 1.1.2reversative or privative prefixes ? 1.1.3 pejorative prefixes ? 1.1.4prefixes of degree or size ? 1.1.5prefixes of orientation and attitude ? 1.1.6locative prefixes ? 1.1.7prefixes of tie and order ? 1.1.8number prefixes ? 1.1.9conversion prefixes ? 1.1.10miscellaneous prefixes

表示否定意义的前缀常用的有dis-, il-, im-, in-, ir-, mis-, non-, un-等,在单词的前面加这类前缀常构 成与该词意义相反的新词。e.g: ? agree同意→ agree 同意 ? fair公平的→ fair 公平的 ? possible可能的→ possible 可能的 ? understand理解→ understand



? 表示其他意义的前缀常用的有a-(多构成表语形容 词), anti- (反对;抵抗), auto- (自动), co- (共同), en- (使), inter- (互相), re- (再;又), sub- (下面的; 次;小), tele- (强调距离)等。e.g:
? ? ? ? ? ? ? ? ? ? worker工人→ co-worker 同事,帮手 large 大的→ enlarge 使变大 operate工作→ cooperate 合作 write写字→ rewrite 重写 way路→ subway 地铁

?1.2 suffixation
? Suffixation is the formation of new words by adding suffixes to bases . Unlike prefixes which primarily effect a semantic modification of the base ,suffixes have only a small semantic role ,their primary function being to change the grammatical function of the base ,i.e. the change of the word class with a slight modification of meaning.

?1.2 suffixation ?The suffix in the first case will be referred to as a deverbal noun suffix while that in the second will be called a denominal noun suffix.

?1.2 suffixation

?后缀 ?给单词加后缀也是英语构词的一种重要方 法。后缀通常会改变单词的词性,构成意 义相近的其他词性;少数后缀还会改变词 义,变为与原来词义相反的新词。

?1.2 suffixation
? (1)构成名词的后缀常用的有-ence,-(e)r/ -or (从 事某事的人),-ese (某地人),-ess (雌性),-ian (精 通……的人),-ist (专业人员),-ment (性质;状 态),-ness (性质;状态),-tion(动作;过程)等。 例如: ? differ不同于→difference区别 ? write写→writer作家 ? China中国→Chinese中国人 ? act表演→actress女演员 ? music音乐→musician音乐家

?1.2 suffixation
? (2)构成动词的后缀常用的有-(e)n (多用于形容词 之后),-fy (使……化),-ize (使……成为)。例如: ? wide→widen加宽 ? beauty→beautify美化 ? pure→purify提纯 ? real→realize意识到 ? organ→organize组织 ? sharp→sharpen使变锋利

?1.2 suffixation
? (3)构成形容词的后缀常用的有-al,-able (有能力 的),-(a)n(某国人的),-en (多用于表示材料的名词 后),-ern (方向的),-ese(某国人的),-ful,-(ic)al, -ish,-ive,-less (表示否定),-like (像……的),-ly, -ous,-some,-y (表示天气)等。例如: ? nature自然→natural自然的 ? reason道理→reasonable有道理的 ? America美国→American美国的 ? China中国→Chinese中国人的 ? gold金子→golden金的 ? east东→eastern东方的 ? child孩子→childish孩子气的 ? snow雪→snowy雪的

?1.2 suffixation
? (4)构成副词的常用后缀有-ly (主要用于形容词之后 表示方式或程度),-ward(s) (主要用于表示方位的 词之后表示方向)。例如: ? angry生气的→angrily生气地 ? to到→towards朝……,向…… ? east东方→eastward向东 ? (5)构成数词的后缀有-teen (十几),-ty (几十),-th (构成序数词)。例如: ? six六→sixteen十六→sixteenth第十六 ? four四→forty四十→fortieth第四十

? Compounding (or composition) is the formation of new words by joining two or more bases. Words formed in this way are called compounds. So a compound is a ?lexical unit consisting of more than one base and functioning both semantically as a single word?. Compounds can be written solid (silkworm) , hyphenated (honeybee) , and open (tear gas and easy chair) . The separation or lack of it in writing is a fair indication of how deeply the heat of fusion has penetrated, and of how much the individual component has kept of its own identity.
