tekerleklerini

Tekerleklerini is a Turkish word form that functions as a definite direct object meaning “their wheels” when referring to wheels belonging to a plural subject. It is produced from tekerlek (wheel) by adding the plural suffix -ler to form tekerlekler, then the third-person plural possessive suffix -leri, and finally the accusative suffix -i to mark a definite object. The typical suffix order in Turkish is plural, possessive, then case; so tekerleklerini encodes “their wheels” as a direct object.

In Turkish, different suffixes can shift the meaning of a noun phrase without changing the root, so tekerleklerini can be used to indicate wheels owned by multiple people or groups and treated as the object of a verb. This form often appears in contexts involving actions on the wheels, such as changing, repairing, or inspecting them. For example: Onların tekerleklerini değiştirdik. (We changed their wheels.) Bu otomobilin tekerleklerini kontrol etmeliyiz. (We should check the wheels of this car.)

Related forms illustrate the system of suffixes. tekerlekler means “wheels” as a plural subject or generic noun, while tekerleklerini or tekerleklerini (with different sentence structures) demonstrate how possessive and accusative suffixes interact to mark ownership and objecthood. Understanding tekerleklerini helps illustrate Turkish noun inflection, where suffixes accumulate to specify number, possession, and grammatical case on a single stem.
