Hungarian builds several pronoun families around three interrogative bases: ki “who,” mi “what,” and melyik “which one.” Prefixes create existential valaki/valami, free-choice bárki/bármi, and negative senki/semmi. Case endings attach to the whole pronoun, producing forms such as kivel “with whom,” valakinek “to someone,” and semmiről “about nothing.” Negative forms participate in negative concord, so senki requires nem/sem rather than replacing clause negation.
The three interrogative bases
| Base | Core reference | Typical question |
|---|---|---|
| ki | person: who? | Ki telefonált? |
| mi | thing, event, content: what? | Mi történt? |
| melyik | one selected from a relevant set: which one? | Melyik a tiéd? |
Ki hagyta nyitva az ablakot?
Who left the window open?
Mi van ebben a dobozban?
What is in this box?
Melyik busz megy a pályaudvarra?
Which bus goes to the railway station?
Ki expects a human answer. Mi asks for the identity or nature of a nonhuman entity, event, or proposition. Melyik presupposes a choice among salient alternatives and can modify a noun (melyik busz) or stand alone (melyik?).
The spelling mi is also the first-person plural subject pronoun “we.” Syntax and intonation disambiguate: Mi történt? asks “What happened?”, while Mi indulunk először means “We are leaving first,” with contrastive mi.
Case forms of ki, mi, and melyik
The interrogative bears the case required by its role. Hungarian does not use a preposition plus an unchanged question word.
| Relation | ki | mi | melyik |
|---|---|---|---|
| nominative | ki | mi | melyik |
| accusative | kit | mit | melyiket |
| dative | kinek | minek | melyiknek |
| instrumental | kivel | mivel | melyikkel |
| inessive | kiben | miben | melyikben |
| elative | kiből | miből | melyikből |
| sublative | kire | mire | melyikre |
| delative | kiről | miről | melyikről |
| allative | kihez | mihez | melyikhez |
Kinek küldted el a fényképeket?
Who did you send the photographs to?
Mivel nyitottad ki az üveget?
What did you open the bottle with?
Melyikből kérsz még egy szeletet?
Which one would you like another slice from?
The instrumental -val/-vel assimilates after consonant-final melyik, giving melyikkel with long kk. Vowel-final ki/mi give kivel/mivel. Vowel harmony supplies forms such as kiből, miről, kihez; every long vowel and double consonant is meaningful.
Possessive -é creates kié? “whose?”, mié? “belonging to what?”, and melyiké? “which one’s?”. These can take further case or plural marking: kiét “whose one” as an object, kiéi “whose ones.”
Kié ez a vizes esernyő?
Whose is this wet umbrella?
Question words occupy the focus position
An interrogative constituent normally stands immediately before the finite verb. A verbal prefix then follows the verb.
Kit hívtál fel ilyen későn?
Who did you call so late?
Miről beszéltek a folyosón?
What were they talking about in the corridor?
In Kit hívtál fel?, focused kit causes fel to stand after hívtál. This word order is structural, not an optional stylistic inversion copied from English.
Accusative kit/mit normally select the indefinite verb paradigm: Kit vársz? Mit olvasol? Set-selecting melyiket selects the definite paradigm: Melyiket választod? This contrast is a principal exception learners must memorize.
Building existential, free-choice, and negative families
| Function | Person | Thing | Selection |
|---|---|---|---|
| interrogative | ki | mi | melyik |
| existential/unspecified | valaki | valami | valamelyik |
| free choice | bárki | bármi | bármelyik |
| emphatic free choice | akárki | akármi | akármelyik |
| negative | senki | semmi | semelyik (less frequent) |
Valaki/valami assert that an unspecified entity exists. Bárki/bármi remove restrictions: every eligible person or thing is an acceptable choice. Akárki/akármi often adds stronger “absolutely anyone/anything” or, in some contexts, dismissive “just anybody.” Senki/semmi supply a negative associate but do not remove the negative particle from the clause.
Valaki kopog az ajtón.
Someone is knocking at the door.
Bárki jelentkezhet a tanfolyamra.
Anyone can apply for the course.
Senki sem tudta a helyes választ.
Nobody knew the correct answer.
The prefixed forms behave as single orthographic words. Their case ending follows the entire compound: valakit, valakinek, valakivel; bármit, bármiről; senkit, semmiben.
Találkoztál valakivel a konferencián?
Did you meet anyone at the conference?
Ezt bárkinek elmondhatod.
You can tell this to anyone.
Semmiről sem szeretnék elhamarkodottan dönteni.
I would not like to make a hasty decision about anything.
The relational form is not split: valaki-vel is only a classroom segmentation, never Hungarian spelling.
Negative concord is part of the form system
Standard Hungarian requires clause negation with a negative pronoun. Nem can negate the predicate directly; sem (or colloquial se) serves as the concord marker immediately after a preverbal negative constituent. In this construction, sem does not by itself make the exclusion stronger than nem.
Senki nem szólt előre a változásról.
Nobody warned us about the change in advance.
Senki sem maradt az épületben.
Nobody remained in the building.
Nem találtam semmit a fiókban.
I found nothing in the drawer.
English formal usage normally avoids a negative verb with “nobody/nothing.” Hungarian requires the concord: Senki maradt and Találtam semmit are incomplete as ordinary negative clauses.
Negative pronoun objects select the indefinite conjugation: Nem ismerek senkit, not nem ismerem senkit. Their semantic negativity does not make them grammatically definite.
Fused personal answers to case questions
Question forms such as kinek, kivel, kiről are case-marked interrogatives. A personal answer usually comes from a fused relational paradigm, not from nominative én/te/ő plus a copied suffix.
– Kinek adtad a kulcsot? – Nekem.
– Who did you give the key to? – To me.
– Kivel mész a koncertre? – Vele.
– Who are you going to the concert with? – With him/her.
Nekem answers kinek, and vele answers kivel. These belong to the fused paradigms described under accusative and dative personal forms and local personal-pronoun series; forms such as énnek and ővel are not neutral. Nominative personal subjects, meanwhile, are normally omitted when verb endings identify them: Kivel mész? – A nővéremmel megyek, not mechanically Én a nővéremmel megyek unless “I” is contrasted.
Principal lexical and register notes
Valamelyik means one unspecified member of a known or imaginable set. Valamely is an article-like (formal) determiner meaning “some”: valamely jogszabály alapján “under some legal provision.” Everyday speech generally prefers valamelyik with a concrete set or egy with a newly introduced singular noun.
Valamelyik fiókban biztosan van egy tartalék kulcs.
There is surely a spare key in one of the drawers.
Bárki is neutral free choice. Akárki can be equally neutral when emphasizing unrestricted choice, but with stress it can sound dismissive: Ő nem akárki means “He/she is not just anybody.” Colloquial (informal) se often alternates with sem: Senki se jött el. Formal writing normally favors sem in that position.
Segmentation exercise
- kit = ki-t, interrogative person + accusative.
- melyikkel = melyik + -vel, with v assimilating and final k doubling.
- valakinek = vala-ki-nek, existential prefix + person base + dative.
- valamiből = vala-mi-ből, existential prefix + thing base + elative.
- bárkivel = bár-ki-vel, free-choice prefix + person base + instrumental.
- senkiről = sen-ki-ről, negative person base + delative.
- semmivel = sem-mi-vel, negative thing base + instrumental; mm is preserved.
- nekem = fused dative personal form answering kinek?, not én-nek.
Common Mistakes
❌ Ki vel beszéltél a recepción?
Incorrect — the case-marked interrogative is written as one word, kivel.
✅ Kivel beszéltél a recepción?
Who did you speak with at reception?
❌ Melyiket választasz a három közül?
Incorrect — melyiket selects the definite verb paradigm.
✅ Melyiket választod a három közül?
Which of the three are you choosing?
❌ Senki érkezett meg időben.
Incorrect — a negative pronoun requires clause negation.
✅ Senki sem érkezett meg időben.
Nobody arrived on time.
❌ Nem ismerek valakit ebben a városban.
Wrong for 'I do not know anyone' — valakit means a particular unspecified someone.
✅ Nem ismerek senkit ebben a városban.
I do not know anyone in this city.
❌ Kinek adták? – Énnek.
Incorrect — a personal dative answer uses the fused form nekem.
✅ Kinek adták? – Nekem.
Who did they give it to? – To me.
Key Takeaways
- Ki asks about people, mi about things/content, and melyik selects from a set.
- Case endings create single words: kivel, miről, melyikhez.
- Valaki/valami are existential, bárki/bármi are free-choice, and senki/semmi are negative.
- Negative pronouns require negative concord with nem/sem and normally select indefinite verb forms as objects.
- Open kit/mit take indefinite verbs; set-selecting melyiket takes a definite verb.
- Case questions often receive fused personal answers: Kinek? – Nekem. Kivel? – Vele.
- Recoverable personal subjects remain omitted unless discourse contrast requires them.
