Is くれ the short form for くれる?

Question

In the following sentence:

ペンを貸してくれ。

Is くれ the short form for くれる?

Answer 1

What do you mean by short form? Usually that's another name for 辞書形｛じしょけい｝ or the 'dictionary form', which くれる already is in itself. It's not an abbreviation, either; rather くれ is the irregular 命令形｛めいれいけい｝ 'imperative' of くれる. It's a little lighter as a command than 「ペンを貸せ」 would be, but not so much as 貸して or 貸してください
