quesion on middle eastern titles for Kings..

hello: my nae is Ibrahim, and I'm a bit new here, so bear with me:

I am currently studying titles used in the middle east in the period of the rise of Ashur. I already know the akkadian, hebrew, phoenician, hittite, and several other languages for "King"(akkadian for king sounds like Arabic for "evil"). but I cannot find the word for king or crown prince in the following:

 

1-Luwian

2-Elamite (also want a dictionary source)

3-Phrygian

4-Hittite (for prince only)

does anyone know these words?

 

also, I've been trying to find a good book or websource or advice at least, to teach me how to differentiate between verb classes (a/u, a/a, a/i, etc), without having them given to me, or is it random?

 

thanks in advance.
