六大英语构词法详解

英语构词通常包括六种方法:转化法、派生法、合成法、混合法、截短法和首尾字母结合法。 一、【派生法】 英语构词法中在词根前面加前缀或在词根后面加后缀,从而构成一个与原单 词意义相近或截然相反的新词的方法叫作派生法。 1. 前缀 除少数英语前缀外,前缀一般改变单词的意义,不改变词性;英语后缀一般改变词类,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。例如: agree 同意→disagree 不同意 fair 公平的→ unfair 不公平的 possible 可能的→ impossible 不可能的 understand 理解→misunderstand 误解 (2)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。例如: co-worker 同事,帮手 enlarge 使变大 cooperate 合作 rewrite 重写
