The subjunctive mood is dead. Long live the indicative. Ooops: I used the subjunctive there!
Well, apart from certain well-known expressions, it is dead. Requiescat in Pace (that's Latin - the subjunctive's OK in Latin - and in any case, that entire language is dead).
It's dead in Britain, anyway. In American English, it has held on - grimly - up to now, and it is even referred to as "the American Subjunctive".
Who says, "He wished he were bigger" when "He wished he was bigger" is a much more sensible statement. No-one. Not in Britain, anyway. There's no need for it. It adds nothing. I doubt it even adds much poetically. So let's have done with it, and use it no more.
I mean - it only exists in the verb "to be": I be/were, you be/were, he be/were, and so on. It doesn't exist in any other verb, except in the 3rd person singular present, where the final "s" is dropped. (In Britain, to drop the "s" could be seen as an affectation except in the most formal of writing - The Committee resolved that the Chairman decline the invitation ...)
Except ... due to the ever growing predominance of American English (at least until it morphs into Spanglish) the subjunctive is creeping back and insinuating itself everywhere - even here in UK. Is that a good thing or not?
