Dear Renas, please stay on the subject.     
You're drifting away saying things should be bilingual etc.. but this goes against what you did in this changeset when you changed node 2488268902 from having Arabic name to Kurdish. If you want bilingual then why did you changed it to be only in Kurdish? If there is nothing wrong with your edit then please provide a reason and source for this node.       
And about the lake, it's a lake, not a city or village, no one live in the lake other than the fishes, the fishes doesn't speak a language, therefore the name of the lake should be in the spoken language in state.       
Best Regards.
