Hi evryone, When is it appropriate to use the word guy? Thanks.
Use "guy" only when speaking or in informal writing. Don't use it in things like academic essays. It's an informal word.
it is still more used in the US thanthe UK -

in the UK, if you address a crowd as "you guys", people are likely to think you are being playful with language - it doesn't sound serious at all to most of us!

One use would be to refer to a man as in " I miss my guy".
