Hej

I don't regard imperatives as interjections. The literal translation is "disappear!", would you regard that as an interjection? I don't think so.

We both should know that literal translations aren't what is used in common practice. Moment is literally "eye blink" but you don't hear anyone saying eye blink. ;)

I have no idea why go away has an interjection section, since it is clearly an imperative. go, run or stop could just as easily claim to be interjections.

If you feel strongly about it by all means go ahead and revert my change, but I think it is stupid (no offence).

I also consider a possible reversion of Leo's edit not quite sound. To mine understanding, go away and forsvind are explicable by regarding them as imperative forms, whereas begone, lo etc. are not. There is a clear distinction between those two cases and yours belongs to the first group.
