Why not "Bir ay otuz günLER"?
The plural suffix is never used after numbers. It is simply not correct in Turkish :)
Got it! Thanks!
I asked this in another discussion, but just in case that doesn't get answered, can one say "bir ayın otuz günü var" to mean "one month has thirty days?"
You could definitely say it (it's gramatically correct) but most people would prefer to say "bir ayda otuz gün vardır" :)
Thank you! So is saying "bir ayda otuz gün vardır" also more common than "bir ay otuz gündür?"
No, these are equally used. You're welcome!
Başka bir ay otuz bir gündür.
