It is because of conjugation. Look at this:
1. Ben yerim
2. Sen yersin
3. 0 yer
1. Biz yeriz
2. Siz yersiniz
3. Onlar yerler
Hope I helped and you'll finally get it. Good luck.
It is true
why is it wrong to say "kizi limonu yer" ?? it says "the girl" so it should be kizi ...
The girl (nominative) eats (verb) the lemon (direct object-in accusative case).
Kız (nominative) limonu (accusative-direct object) yer (conjugated verb).
Best example thanks
no, that would make it accusative and it can't be accusative here.
But "limonu" is in the accusative, right? "kız" is the subject of the sentence so it shouldn't be inflected anyway.
got it thanks
why there can´t be "bir kiz" as the is the deffinite article "the girl"?
Duolingo usually accepts both. But normally, people would usually use 'kız' alone for mentioned one. If not they would state that using 'bir'. And 'bir' is not an article but an indefinite adjective.
Why not limoni??
This is because of 4-way vowel harmony. You can read more about it here or in the Tips and Notes before the lesson if you are on the website: https://www.duolingo.com/comment/9041808
Why is it not "kızı"?
Why not limon?
Why yer and no yersiniz?
Becuase "Yer" means "eats" and refers to He/she/it, while "yersiniz" means "You eat (plural)"
Why yer not yersun
Why it s wrong i writ kiz limonu yer ?
