"They will come to the park with us."

Translation: Onlar bizimle parka gelecekler.

[NedFlander1]

I wrote "Onlar bizimle parka gelecek" and is was marked wrong. Can somebody tell me why the "ler" is important in this sentence.

Thanks

[Selcen_Ozturk]

it is not, there are missing alternatives for sure

[Sotirakis1]

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"

[Magi676120]

Parkta is in,on or at the park. Parka is to the park.

[MaxamadIbr]

bizimle onlara parka gelecekler
They will come to the park with us.
what is wrong with that ?

[AlexinNotTurkey]

You wrote "onlara" which is in the dative case. Subjects cannot be in the dative case.
