Como dizer "a maioria" em inglês

Thank you very much donay
It's good to have a place where we can have our questions answered. I don't know what I would do without this forum.

Keep up the good work!!

Sorry, but I was thinking here and I see that I don't know if exist any difference between Mostly and Mainly... Are there any difference in the meaning ?

I've noticed that I can use Mostly to say: "Maioria das vezes, algo que ocorre geralmente"
I've noticed too that I can use Mainly to say: "Algo é principal, que possui um alto nível"

Am I correct? Can someone explain it to me?
