I am a newcomer and happy that I am here.
Is it possible to use anybody / anyone at the beginning of the sentence as subject in different types of sentences (?, +. -)?
For example: Anybody can't go out.
or do we have to use nobody?
Welcome to the forum, English4everyone.
You can use 'anybody' at the beginning of a sentence - "Anybody who thinks you can't use it is wrong" - but not in the way you have. That has to be "Nobody can go out."
