Or is Woman another word for a girl?
And when does a boy become a man?

That depends. Physically you could say a girl is a woman when her period starts. For me that was 12 years old but some are younger and most I think are a little older. Mentally however it's anyones guess. It really runs parallel to the question when is someone amd adult. There is an age that someone is legally recognized as an adult but when they actually start acting like it is quite another thing entirely. The same could be said for when a girl becomes a woman. I think it all depends on how you define it which can be different from person to person0
