有时两个单词组合在一起可以构成一个新的单词，这类词叫合成词，也叫复合词。复合词有的需要在两个单词之间加连字符“-”，有的则不需要。
★“名词 + 名词”或“形容词 + 名词”可以合成名词。例如：
class + room → classroom
black + board → blackboard
★“名词 + 形容词”或“形容词 + v-ing形式”可以合成形容词。例如：
world + famous → world-famous
easy + going → easy-going
★“副词+动词”或“形容词+动词”可以合成动词。例如：
over + sleep → oversleep
white + wash → whitewash
并不是任意两个单词都可以组合成一个复合词，因为复合词有特定的含义，所以要随时学，随时记，经常总结和归纳学过的复合词。
