hatásukat

Hatásukat is a Hungarian word formed from the noun hatás ("effect, impact") with third-person plural possessive and accusative suffixes; it literally means "their effect" used as a direct object. Morphologically it breaks down as hatás (stem) + -uk (third-person plural possessive, chosen by vowel harmony) + -t (accusative/object marker), producing hatásukat. Vowel harmony governs the choice of the possessive suffix in Hungarian: after back vowels like a, o, u the suffix is -uk (compare with -ük after front vowels).

Functionally, hatásukat appears when referring to the effects or impacts that belong to a plural possessor and when that notion is the object of the verb. It often occurs alongside an explicit possessor noun for emphasis or clarity (a so-called double-marking): for example, A kutatók vizsgálták a vegyszerek hatásukat — "The researchers examined the chemicals' effects." Without the possessive suffix one can also express possession via a genitive construction (a vegyszerek hatása).

Pronunciation is approximately [hɒtaːʃukat]. Usage notes: the form is grammatically specific to third-person plural possessors and can vary when number, person, or vowel harmony differ; related forms include hatásuk (their effect as subject) and hatásom/hatásodat (first/second-person forms).
