I'm currently working at a private academy in Korea, and my boss just asked me a real head-scratcher.
In the sentence:
It doesn't have to be hot and humid for players to lose too much water from their bodies.
I'm aware that "It" is a subject pronoun replacing "The weather." Besides that, however, I'm unsure.
Is it a false subject? I wouldn't think so since it's a pronoun. Is it some crazy kind of indirect object?
Anyway, thank you all for your help!
