Personal Infinitives (mennem, menned)

Grammar Rule in 30 Seconds

Personal infinitives allow you to attach a person suffix to an infinitive to show who must perform the action.

  • Add possessive suffixes to the -ni infinitive: mennem (I must go).
  • Use these forms primarily with 'kell' (must) or 'szükséges' (necessary).
  • The subject is implied by the suffix, so you rarely need a pronoun.
Verb-ni + Suffix (m/d/a/unk/tok/uk) = Personal Infinitive

Focus on the suffix

Don't try to memorize the whole word. Just learn the suffixes -m, -d, -i, -ünk, -etek, -iük.
⚠️

Kell is invariable

Never conjugate 'kell'. It is always 'kell', regardless of the person.
🎯

Use it for 'I have to'

This is the most natural way to say 'I have to' in Hungarian.
💬

Keep it short

In casual speech, you can drop the 'kell' if the context is obvious.

Smart Tips

Don't use 'hogy'. Just use the personal infinitive.

Kell, hogy menjek. Mennem kell.

Think of the possessive 'my' (enyém -> -m).

Menni kell. Mennem kell.

Change 'kell' to 'kellett'.

Mennem kell volt. Mennem kellett.

Use 'kellene' instead of 'kell'.

Mennem kell. Mennem kellene.
