英语构词法
英语构词法主要有三种：合成、转化和派生。
★合成是指将两个意思不同的单词结合成一个
新词。这类词可以由“名词+动词”、“名
词+名词”或“形容词+名词”等构成。如：
①名词+动词：breast + feed?→?breastfeed
②名词+名词：note + book?→?notebook
③形容词+名词：blue + berry?→?blueberry
④动词+名词：work + room?→?workroom
⑤形容词+动词：high + light?→?highlight
⑥动词+副词：break + up?→?breakup
★转化是指一个单词的词形不经过任何变化而
由一种词性转化为另一种词性。如：
①名词转化为动词：ship (n.)?→?ship (v.) (to
send or transport sth. /sb. in a ship)
②形容词转化为动词：green (adj.)?→?green (v.)
(to make ... environmentally friendly)
③介词转化为名词：the?ups?and?downs?of life
④连词转化为名词：no?ifs, ands, or?buts
★派生是指通过给一个单词加前缀或后缀构
成另一个词。（前缀一般改变词义而不改变
词性，后缀一般改变词性而不改变词义）如：

注意：

的词之间用连字符连接。如：

office high-speed, CD-ROM, warm-up
2.?合成形容词被视为一个单词，常放在所修饰
词的前面。如：

the chair?
My neighbour is a?kind-hearted?lady.
