What does ya mean in Arabic?

Answer 1

Ya is kind of like you but kind of different since it's used to call someone something example: "You are a person", or "You are my sweetheart"

It is also an Arabic letter (which is equivalent to the English Y).

Answer 2

Answer 1 is correct that "Ya" is an Arabic letter. However, the first part of the definition is confusing, see below for a better explanation.

English has lost the equivalent particle to ya (يا) in speech, but the best way to translate it would be "O" as in "Listen to me well, o' King." It directs attention to the recipient of a command.
