"Hoşça kal ve bütün balıklar için teşekkürler."
Translation:So long and thanks for all the fish.
Switchable plurals & you should know this having reached level (18)
And yesterday I saw you standing by the river. And weren't those tears that filled your eyes. And all the fish that lay in dirty water dying. Had they got you hypnotized?
Led Zeppelin - "That's the way."
Song to remind you of switchable plurals & non quantifiable - Fish.
