Gildor in Quenya

I want to translate Gildor's name in Quenya.

The -dor suffix is -tur, but I'm not sure about Gil.

I know it means star, but the "el" root is similar in Quenya and Sindarin, so if it was El--tur in Q., it would have been translated as El--dor in S. (I'm making him a character who was a quenya-speaker first).

Are there other words in quenya with similar meanings, and phonetics closer to Gil, that could have been translated that way ?

Thanks
