What is the origin of the word Ur which used to be a thriving Metropolis in now day Iran?

I been having this question ever since I heard the name of the Town Ur in history class. Is that a coincident that Ur means lord in Hungarian? "The city's patron deity was Nanna, the Sumerian moon god, and the name and of the city is in origin derived from the god's name URIM" took this from wikipedia http://en.wikipedia.org/wiki/Ur ,but the point is that URIM if you replace the "I" with an "A" than you get URAM which means my/our Lord. So the city was named after a god who was called god in Hungarian. Maybe all this is just an interesting coincident =P
