funkciójuk

Funkciójuk is a Hungarian term that translates roughly to "their function." It is formed from the noun funkció (function) plus the third-person plural possessive suffix -juk (or -jük, depending on vowel harmony). The suffix attaches to the stem to indicate that the function belongs to multiple subjects. In standard spelling, the ending reflects the harmony of the stem, so funkciójuk is typical for stems with back vowels, while front-vowel stems would take -jük.

The term is used in linguistic and everyday Hungarian to refer to the function or role of several entities collectively. It serves as a possessive noun phrase and can function as a subject or object within a sentence, much like other possessive constructions. For example: "Ezeknek a készülékeknek a funkciójuk az adatgyűjtés." (The function of these devices is data collection.) Another example: "Megvizsgálták a funkciójukat." (They examined their function.)

Funkciójuk has related forms that reflect case and number, such as funkciójukat (accusative: their function), funkcióik (their functions), and funkcióikban (in their functions). It is distinct from funkciója (his/her function) and funkcióit (their functions in the accusative, depending on context). The word illustrates how Hungarian combines a base noun with possessive suffixes to express relationship to multiple subjects, while remaining flexible for different syntactic roles.
