再问"However"

我查了所以我能查的帖子，觉得没有把这个问题说清楚：

However在做副词，当 no matter how讲时为什么可以连接句子？

However做副词有两种意思
1) nevertheless,最常用，不能连接句子－我理解，如:He hasn't arrived. He may, however, come later.
2) no matter how, 多处表明能够连接句子:如 Longman:
You should report any incident, however serious or minor it is.
We'll have to finish the job, however long it takes.
还有 OG10, However much the US voter may agree, it is…

However做连词时，应该是 in whatevery way的意思，此时才应该能够连接句子啊，如，
You can do it however you like.
If we win the match we'll be delighted, however it happens.
However you look at it, it was a wicked thing to do.

 我不理解2) 的情况，既然做副词，为什么还能连句子？我看了OG-10的讨论，至少我没有发现对这一点的明确解释。

没人回答就顶一下！

我查了下，看到有个说法，是however可以引导状语从句，是不是能这样解释呢。

to be discuss

谢谢，版主。

可是，引导从句总得对词性有个要求啊？However做连词时，的确引导的是状语从句，没问题。但为什么那么多字典把它化为副词时(相当于no matter how)，仍然可以引导状语从句呢？

引导状语从句，做伴随状语．．．

应该就是这样的．．．
