I already know that words like "team" that emply a group of people, require "they" when you use a pronoun.
Actually, they don't. You can refer to a team as "it" or "they" depending on your focus.
But what with "anybody", "somebody"? I think it's "they" as well, but can you confirm?
You can use a singular "they" for these if necessary.
Anybody who forgot to bring their assignment, please see me after the class.
And what about words like "mankind". And "progeny"?
I'd use the singular for "mankind"
Thank you in advance.
