I wrote "Onlar bizimle parka gelecek" and is was marked wrong. Can somebody tell me why the "ler" is important in this sentence.
it is not, there are missing alternatives for sure
When I first started listening to Turkish on YouTube, it was pointed out that when you talk about humans you have to add lar/ler.
Why not "parkta"
Parkta is in,on or at the park. Parka is to the park.
bizimle onlara parka gelecekler
They will come to the park with us.
what is wrong with that ?
You wrote "onlara" which is in the dative case. Subjects cannot be in the dative case.
