构词法
1.合成构词法
由两个或两个以上的词合成一个新词，这种构词法叫合成构词法。合成词在英语中比较活跃。合成形容词很常见，多数用作定语，有些作表语；合成名词作主语或宾语；合成动词用作谓语。
合成名词 classroom(名词+名词)
blackboard(形容词+名词)
handwriting(名词+动名词)
afternoon(介词+名词)
合成形容词 worldwide(名词+形容词)
man-made(名词+过去分词)
good-looking(形容词+现在分词)
well-known(副词+过去分词)
合成动词 overcome(副词+动词)
download(副词+动词)
合成数词 fifty-four(数词+数词)
合成代词 somebody(不定代词+名词)
anything(不定代词+名词)
myself(物主代词+名词)
合成副词 downstairs(介词+名词)
whole-heartedly(形容词+副词)
2.派生构词法
在一个单词前面或后面加上一个词缀构成新词，这种构词法叫派生构词法。由此构成的新单词叫派生词，加前缀或后缀的单词叫词根。词根是基础，同一个词根加上不同的词缀可以组成不同意义或不同性质的词。加在单词前面的词缀叫前缀，加在单词后面的词缀叫后缀。前缀多改变词义，后缀多改变词性。
前缀 例词
en-(使) enable，enrich
un-(不，非；表示否定) unfriendly，unpleasant，uncomfortable
dis-(不，非；表示否定) disadvantage，dishonest，disagree
in-(不，非) incorrect，informal
im-(不，非) impossible，impolite
re-(又，再，重来) review，rewrite
后缀 例词
-or /-er /-ian(……人，名词后缀) actor，visitor，singer，musician
-ful(充满的……，形容词后缀) successful，beautiful，colourful，wonderful
-tion(表示动作、状态，名词后缀) invitation，population，prediction
-less(没有、无，形容词后缀) homeless，helpless，careless
-y(表示性质，形容词后缀) healthy，cloudy，windy
-al(……的，形容词后缀) traditional，national，natural
-able(有……特性的，形容词后缀) comfortable，unforgettable
-ness(状态、性质，名词后缀) illness，happiness
-ly(以某种方式，副词后缀) quickly，happily，slowly
3.转化构词法
一个单词由一种词性转换为另一种词性，这种构词法叫转化构词法。单词的形式没有变，只是词性和意思有变化。
(1)名词转化为动词 show n.展览，展示→ show v.表演，展出 book n.书→ book v.预订
(2)形容词转化为动词 slow adj.慢的→ slow v.使放慢
(3)动词转化为名词 walk v.步行→ walk n.步行 swim v.游泳→ swim n.游泳
