kabátját
Kabátját is a Hungarian grammatical form meaning “his coat” or “her coat,” used when the coat belongs to a specific person and is the definite direct object of the verb. The base noun is kabát, meaning coat. The form kabátja marks third-person possession (his/her/its coat), and the additional definite-object suffix -t marks the noun as a definite object within the sentence. The resulting sequence is kabát + ja + t, yielding kabátját.
In practice, kabátját appears in sentences where the coat is both possessed by a known person and
Hungarian also allows related forms for other persons, such as kabátom (my coat), kabátod (your coat), kabátja
Summary: Kabátját is a possessive definite-object construction in Hungarian, formed from kabát plus the third-person possessive
