Most of prescriptive grammars I used to study highlighted the uses of the adverb "already" as being "only" used in affirmative present perfect clauses. Well, and there I came across a sentence which said: " If he DIDN'T already have a girlfriend, I'd ask him out", where we can appreciate neither a present perfect, nor an affirmative clause. I wonder if this is possible? I guess it is, but on what grounds? Thanks a lot for this superb forum. From a Spanish teacher of English (EFL).
