Hebrew uses vowels. They are a series of dots, dashes, and dipthongs, some under, some over, and some beside a letter to change the sound, accent a letter, or break a word. Most people do not realize it, but we also have a writing alphabet that is completely different than the caligraphy used to write Holy Text.
Arabic has the same, though their usage is very different.
I read from the Torah during my Bat Mitzvah.I hope I can do it again.It was amazing.
