把兩個或兩個以上獨立的詞合成一個新詞的方法叫做合成法，也叫合詞法
(1)合成名詞

Cold-blooded hand-made hard-working
(3)合成動詞

(4)合成副詞

(5)合成代詞

2、 轉換法
轉換是指由一種詞類轉化為另一種詞類。
(1)動詞轉化為名詞

(5)形容詞轉化為名詞

3、 派生法
派生法是由詞根加詞后綴構成新詞。構成的新詞稱為派生詞。詞綴分為前綴和后綴。除少數前綴外，前綴一般只改變詞的意義，不改變詞性；后綴一般只改變詞性，不引起詞義變化。
前綴
a- （形容詞、副詞） asleep
dis- （否定） discourage
in-i-im-ir- （不、非） impossible
en- (使可能) enable
mis- (誤) mistake
re- ( 重復、再) return
tele- （遠程） telephone
un-on- (不、非) unfair
后綴
名詞
-er -ese -ian -ist -ment -ness -or -tion
形容詞
-al -an -ern -ful -ble -ish -ive -y -less
動詞
-ly -iza
副詞
-ly -ward(s)
形容詞
-teen -ty -th
