This same root turns up as crescere in Latin and was then applied to the growing moon.

这个词根在拉丁语中以crescere的面目出现，它在后来被用来指称正在成长的月亮。

This ker root found its way into the Latin crescere and from what I can see, somewhere back as Latin was morphing into French this “grow” word was used to build “re-grow.”

根据我的判断，在历史中的某个时期，这个拉丁词根又被引入到法语中，从而参与构词；因此，这个“grow”单词就曾经被用来构建单词“re-grow”。
