allativusának

Allativusának is a Hungarian inflected form used to refer to something belonging to or associated with the allative case. The base term allativus derives from the Latinized grammatical label allative, a case that marks movement toward or direction to a location. In descriptions of Hungarian grammar the allative function is typically realised with the suffixes -hoz / -hez / -höz (e.g., házhoz "to the house", iskolához "to the school").

Morphologically, allativusának combines the lexical stem allativus with a Hungarian oblique/possessive ending (-ának) to yield a phrase meaning "of the allative" or "the allative's ...". It commonly appears in metalinguistic contexts when discussing case forms, markers, or properties: for example, A "ház" allativusának jele a -hoz végződés ("the allative of 'ház' is marked by the suffix -hoz").

Usage is primarily academic and descriptive: linguists, grammarians, and language teachers use the form when referring to features, paradigms, or examples related to the allative case. It is not a lexical item of everyday vocabulary but a grammatical reference that appears in analyses, textbooks, and corpora when Hungarian case morphology is the topic of discussion.
