erfeszítésének

**erfeszítésének** refers to the Hungarian grammatical construct formed by adding the suffix *-ának* to a noun or pronoun, indicating possession or association in the third-person singular possessive case. This suffix is part of the Hungarian language’s complex system of cases, known as *ragozás*, which modifies nouns and pronouns to express grammatical relationships.

The suffix *-ának* is derived from combining the third-person singular possessive suffix *-e* (indicating possession) with the accusative case ending *-t* (though it is often used without the preceding noun being in the accusative form). It is commonly used in contexts where the possessor is a third-person singular entity, such as a person, animal, or abstract concept. For example, *"a könyvének"* (literally "the book of it," meaning "his/her/its book") shows possession by a third-person singular subject.

This form is frequently encountered in spoken and written Hungarian, particularly in relative clauses or when specifying ownership. It can also appear in fixed expressions or idiomatic phrases, though its meaning remains tied to possessive relationships. Unlike some other languages, Hungarian does not use articles or gender distinctions in the same way, relying instead on case endings to convey grammatical roles.

The use of *-ának* reflects the language’s agglutinative nature, where multiple suffixes can be combined to convey complex meanings concisely. While it may appear complex to learners, it is a standard feature of Hungarian grammar, ensuring clarity in possessive constructions.
