ajtaját
The term "ajtaját" refers to a specific Hungarian grammatical construction. It is a possessive suffix that indicates the third-person singular possessor. In Hungarian, possession is often expressed by adding suffixes to the possessed noun, which vary depending on the number and person of the possessor.
