英语的构词法主要有：转化法、派生法、合成法、截短法(缩略法)、混合法(混成法)和首尾字母缩略法。
一 转化法
在英语中，有的名词可作动词，有的形容词可作副词或动词，这种把一种词性用作另一种词性而词形不变的方法叫做转化法。
1. 动词转化为名词：很多动词可以转化为名词，大多意思没有多大的变化(如下①)；有时意思有一定变化(如下②)；有的与一个动词和不定冠词构成短语，表示一个动作(如下③)。
①Let’s g ut fr a walk. 我们到外面去散步吧。
②Let’s have a swim. 咱们游泳吧。
③He is a man f strng build. 他是一个体格健壮的汉子。
2. 名词转化为动词：很多表示物件(如下①)，身体部位(如下②)，某类人(如下③)的名词可以用作动词来表示动作，某些抽象名词(如下④)也可作动词，
①Did yu bk a seat n the plane? 你订好飞机座位了吗？
②Please hand me the bk. 请把那本书递给我。
③She nursed her husband back t health. 她看护丈夫，使他恢复了健康。
④We lunched tgether. 我们在一起吃了午餐。
3. 形容词转化为动词：有少数形容词可以转化为动词。
1.We will try ur best t better ur living cnditins. 我们要尽力改善我们的生活状况。
2.He slwed dwn at the crssrad. 他在十字路口减速。
3.Please warm up the cld meat. 请把冷肉热一下。
4. 副词转化为动词：有少数副词可转化为动词。
Murder will ut. (谚语)恶事终必将败露。
5. 形容词转化为名词：表示颜色的形容词常可转化为名词(如下①)；某些形容词如ld, yung, pr, rich, wunded, injured等与the连用，表示一类人，做主语时，谓语用复数(如下②)。
①Yu shuld be dressed in black at the funeral. 你在葬礼中该穿黑色衣服。
②The ld in ur village are living a happy life. 我们村的老年人过着幸福的生活。
二 派生法
在词根前面加前缀或在词根后面加后缀构成一个与原单词意义相近或截然相反的新词叫做派生法。加在单词前面的词缀叫前缀，加在单词后面的词缀叫后缀。
1. 前缀：除少数前缀外，前缀一般改变单词的意义，不改变词性；后缀一般改变词类，而不引起词义的变化。
（1）表示否定意义的前缀，在单词的前面加这类前缀常构成与该词意义相反的新词。常用的否定前缀有：
（2）表示其他意义的前缀常用的有：
2. 后缀：英语单词不仅可以通过加前缀构成新词，也可加后缀构成新词。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）构成名词的后缀常用的有
（2）构成动词的后缀常用的有
（3）构成形容词的后缀常用的有
【注意】后缀词-ing与-ed的区别：加-ing的后缀词形容词主语一般为物，表示“令人……的”；加-ed的后缀词形容词，主语一般为人，表示“某人感到……”。如：
The mvie was very interesting. All f us were interested in it. 那部电影很有趣。我们所有的人都对它感兴趣。（interesting指的是电影有兴趣，而interested指的是人对电影感兴趣）
（4）构成副词的常用后缀有
（5）构成数词的后缀有
