sérülését
Sérülését is a Hungarian grammatical form derived from the noun sérülés, meaning "injury" or "wound." It combines the third-person singular possessive suffix and the accusative case ending: sérülés (root) + -e (possessive) + -t (accusative) = sérülését. The same surface form may also address the addressee politely, since formal second-person (Ön) uses third-person possessive morphology, so sérülését can mean "his/her/its injury" or "your (formal) injury" depending on context.
Morphologically, sérülés itself stems from the verb sérül ("to be injured") with the nominalizing suffix -és.
Usage spans medical, legal and everyday contexts wherever reference is made to someone's injury as an object.
