What are vocals?

Answer 1

It can mean more than one thing. It can mean your vocal voice, like your sound when you are singing. But it can also mean a certain kind of letters. A, E,I, O,U and Y are vocals. You can now them from their opposite the consonants. That is letters like BCD and so on. They are easy known from the vocals by, that they don't have a sound of their on. Like when you say B you say "be" but when you say A you say a.
