Obligation and permission

Hungarian has a small set of impersonal verbs that never change for person — kell ('must'), lehet ('it's possible/allowed'), szabad ('permitted'), and the everyday muszáj ('really have to') — that pair with a plain infinitive to say what has to, can, or may happen.

To say who is under the obligation, add a personal ending to the infinitive itself: menni ('to go') becomes mennem ('that I go'), menned ('that you go'), mennie ('that he/she go') — the same possessive-style endings you already know from nouns.
