Grammar

英语中很多单词的构成形式是有规律的，掌握单词的构成规律有助于理解和记忆词汇。英语的常见构词法有合成法(Compounding)、前缀法(Prefix)、后缀法(Suffix)和转化法(Conversion)。缩写法和简写法(AbbreviationandSimplification)也是构词法的一种。1.派生法

派生法，又叫词缀法，即在一个单词前或后加上前缀或后缀，构成新的单词。供参考Word-formation构词法

Grammar(1)常见前缀：

有的前缀不仅构成词类的转化，而且还会引起意思上的变化。前缀中有相当一部分可以构成反义词。①表示否定意义的前缀前缀含义例词un­不；非happy→unhappy(不高兴的)usual→unusual(不寻常的)in­不；非active→inactive(不积极的)Word-formation构词法

Grammar前缀含义例词im­不；非polite→impolite(不礼貌的)dis­不；非like→dislike(不喜欢)appear→disappear(消失)non­不；非smoker→non­smoker(非吸烟者)Word-formation构词法

Grammar②其他前缀含义例词mis­错误；失误understand→misunderstand(误解)lead→mislead(误导)re­又；再；重新view→review(复习)write→rewrite(重写)inter­相互；交互；在一起net→Internet(互联网)national→international(国际的)connect→interconnect(相互关联)Word-formation构词法

Grammar(2)常见后缀：后缀通常使词由一种词类转化为另一种词类。①形容词→副词后缀例词＋­lywide→widelyquiet→quietly以“辅音字母＋­y”结尾的形容词，变y为i，再加­lyhappy→happilyangry→angrily以“辅音字母＋­le”结尾的形容词，去掉e，再加­ysimple→simplyterrible→terribly少数以e结尾的形容词，要去掉e，再加­lytrue→trulyWord-formation构词法

Grammar后缀例词＋­yrain→rainyhealth→healthywealth→wealthyluck→lucky＋­lyweek→weeklylove→lovelyfriend→friendly＋­ousdanger→dangerous＋­fulcare→carefuluse→usefulhelp→helpful＋­lessuse→uselesscare→careless②名词→形容词Word-formation构词法

Grammar③动词→形容词前缀例词＋­edinterest→interested＋­ingfollow→followinginterest→interesting＋­tive/­iveact→activeattract→attractive＋­ableenjoy→enjoyablecomfort→comfortableWord-formation构词法

Grammar④形容词→名词前缀例词＋­nesssad→sadnesskind→kindness＋­ydifficult→difficulty＋­ityreal→realitypopular→popularity＋­ce(以t结尾的形容词去t，再加­ce)
