问题描述:

whatever ,however这类词是派生词还是合成词?

两个都是合成词,是疑问词+后缀ever
疑问词的各种用法
no matter +疑问词" 或"疑问词+后缀ever"
例如:
No matter what happened, he would not mind. =Whatever happened, he would not mind.
不管发生什么,他不在意.
替换:
no matter what = whatever
no matter who = whoever
no matter when = whenever
no matter where = wherever
no matter which = whichever
no matter how = however
注意:no matter 不能引导主语从句和宾语从句.
(错)No matter what you say is of no use now.(对)Whatever you say is of no use now. 你现在说什么也没用了.(Whatever you say是主语从句)
(错)*ers have to eat no matter what they're given.
(对)*ers have to eat whatever they're given.囚犯们只能给什么吃什么.
