Learn Turkish: Çiftçinin köpekleri ot yemez. - The farmer's dogs do not eat grass.

yemez is the negative aorist form for the third person. We use the aorist tense to talk about general facts, habits, or things that are always true. Since dogs not eating grass is a general statement about nature, we use the negative aorist suffix -mez instead of the continuous -miyor.

The subject is köpekleri (dogs), which is plural. Why is the verb yemez (singular) and not yemezler?

In Turkish grammar, when a plural subject is not human (like animals, objects, or concepts), the verb usually stays in the singular form. Because dogs are animals, the third person singular negative aorist yemez is used instead of the plural yemezler.

How does the phrase Çiftçinin köpekleri show ownership?

This uses the genitive-possessive construction. Çiftçi (farmer) takes the genitive suffix -nin to mean the farmer's. Köpekler (dogs) takes the third person possessive suffix -i to complete the link.

Why doesn't ot (grass) have an accusative case ending like otu?

We only use the accusative case for specific direct objects, like when talking about a specific patch of grass. Here, the sentence is about grass in general. Because it is a non-specific object, ot stays in its bare dictionary form.
