Hmm, would this not be 'Köpekler topuyla onar' as it is 'the ball'?
no. you cannot combine accusative and instrumental.
topuyla means "with his/her ball" (possessive and instrumental)
Ahh, that's a nicety that has completely passed me by so far. Thank you!
in general you can only have one case - except for possessive.
Why oynar and not oyunlar
Oyunlar is "games" or "Plays". I think, you wanted to say "oynarlar". This would have been also correct.
why the genis zaman is used here? as the English sentence is quite specific about THE dogs I would expect that they ARE playing, hence oynuyor.
I had the same question. Thank you Selcen.
