Using Deep Seek to understand the grammar. I'm surprised how well it explains. Anybody else?
In the sentence "Nem kell fizetnie." ("You don't have to pay." / "He/She doesn't have to pay."), the word fizetnie breaks down like this:
· fizet = the verb stem meaning "to pay"
· -ni = the infinitive suffix (equivalent to English "to ___")
· -e = a possessive/personal suffix referring to a third-person possessor
So fizetnie literally means something like "his/her/its paying" — i.e., the infinitive with a personal possessive marker attached.
Why is it used here?
In Hungarian, after certain auxiliary-like words expressing necessity, obligation, or possibility — such as kell (must/need), lehet (may/can), szabad (allowed), tilos (forbidden) — the infinitive takes a personal ending that agrees with the subject of the sentence, rather than appearing in its bare dictionary form (fizetni).
So instead of:
· Nem kell fizetni. (also possible, more impersonal/general)
you get:
· Nem kell fizetnie. — where -e specifies that the obligation (or lack of it) applies to a particular third person (ő = he/she) or to a formal "you" (Ön).
Concretely:
Person Form Meaning
én fizetnem I don't have to pay
te fizetned you (informal) don't have to pay
ő / Ön fizetnie he/she/you (formal) don't have to pay
mi fizetnünk we don't have to pay
ti fizetnetek you (plural) don't have to pay
ők / Önök fizetniük they / you (formal plural) don't have to pay
So fizetnie = "for him/her to pay" / "his-her paying" — the infinitive carrying the third-person (or formal second-person) ending required by kell.
