英语语法分析

Stammer meant then what it means today, but stut seems to have had a meaning of banging into things.

Stammer在当时的含义同于今天的含义，不过stut似乎曾经含有一种撞到什么东西的意思。

But there was a Middle English stut that came before with the same meaning, and that can be traced to Germanic roots.

不过，在此之前，有个中世纪英语单词stut具有同样的含义，而且可以追溯到日耳曼语根源。
