I have a question about the use of the subjunctive in if clauses. I usually use grammarly as a grammar checker and ran into following problem:
I wrote: If he stay at home, he would die.
Grammarly corrects me to: If he stays at home, he would die.
I remember that I learned in school to use the simple present/past for if clauses (depending on how likely a condition is).
But then, you say "If I were you", not "If I was you", which is clearly subjunctive.
Doesn't that mean the subjunctive form would be grammatically preferable to the simple present? So "stay" is correct, while "stays" isn't?
Or where am I wrong here?
