Talk:as if

I've been arguing with a friend about the second usage for a long time, thanks to whoever traced it to 1903.

They worked as if crazy/mad
Like "as if" is standard in informal speech and writing with some adjectives: They worked like crazy/mad.

Would They worked as if crazy/mad be grammatical though? --Backinstadiums (talk) 18:09, 26 June 2021 (UTC)
