The Hungarian Correlative System: Forms and Core Pattern

Hungarian often builds a complex sentence with two pointing expressions. A demonstrative in the main clause opens a semantic slot—person, thing, time, place, quantity, or manner—and a relative expression identifies its content. Thus az–aki links a person to “who,” azt–amit links an object to “what,” and akkor–amikor links “then” to “when.” English frequently uses only a relative word, so its Hungarian demonstrative partner can feel redundant even though it has an important structural and discourse role.

The labels below show common pairs, not inseparable two-word conjunctions. The demonstrative may be omitted when its role is recoverable, and both members take forms required by their own clauses.

The system intersects with ordinary noun-modifying relatives but is not identical to them. See the relative-clause forms page for clauses built around an overt head noun.

The core paradigm

The relative forms begin with a- in modern standard Hungarian: aki, ami, amikor, ahol, amennyi, ahogy. This element is part of the word. It is not the definite article, and it is not separated in spelling.

Person: az–aki

Use the aki series when the relative expression refers to a person. The correlate is a form of distal az shaped by its role in the main clause.

In the first example, both aki and az are subjects, so both are nominative. In the second, azt is the definite object of hívd vissza, while aki is the subject of üzenetet hagyott. The two cases therefore differ.

Plural reference can use akik when a genuinely plural group is intended:

The pair azok–akik agrees in number because both sides refer overtly to a plural set. This is different from case: number reflects the referent, while each clause assigns its own syntactic case.

Things and propositions: az–ami

Use the ami series for things, content, and sometimes whole situations. When both expressions are objects, the frequent pair is azt–amit.

Both azt and amit are accusative here, but for independent reasons: azt is the object of “ordered,” and amit is the object of “recommended.” The main verb has definite conjugation, rendeltem, because its object is definite.

The cases need not match:

Main-clause válaszol valamire requires sublative arra “to that.” Inside the relative clause, kérdez valamit takes accusative amit. English “what” hides both relations.

Time, place, quantity, and manner

Adverbial pairs make the semantic dimension especially transparent.

In annyi süteményt, quantity word annyi modifies a noun and the noun bears accusative -t. When it stands alone as the object, it becomes annyit: Annyit vigyél... Relative amennyi behaves similarly: amennyi elfogy as subject, but amennyit megeszünk as object.

Place distinguishes rest, destination, and source. The static pair is ott–ahol. Direction toward a place uses oda–ahová, and origin uses onnan–ahonnan. These are lexical members of a paradigm, not forms made by attaching a visible case suffix to ott.

English uses “where” for rest, goal, and source. Hungarian preserves the directional contrast in ahol/ahová/ahonnan, while the main correlate independently chooses ott/oda/onnan.

How case forms are built

The personal and thing relatives accept ordinary case suffixes: akit, akinek, akivel, amiről, amihez. Vowel harmony and consonant assimilation apply normally: aki + -val/-vel → akivel, ami + -val/-vel → amivel.

Forms of demonstrative az are less transparent and must be learned as a family: azt, annak, abban, abból, ahhoz, arról, annál, azért, azzal. They preserve the distal a- but show consonant alternations and doubling. Do not create forms such as aznak or azvel.

Most importantly, semantic pairing does not mean mechanical case copying:

Kér valakitől supplies ablative attól in the main clause; bízik valakiben supplies inessive akiben in the relative clause. Both pronouns identify one person, yet their cases correctly differ.

Clause order and omission

The relative clause can come first as a topic, followed by its demonstrative associate:

It can also follow the main clause:

Hungarian places a comma at the clause boundary in both orders. The first order creates an explicit “as for what...” topic and normally benefits from overt azt. The second can omit the correlate because the object position is recoverable, but the main verb remains definite: elküldtük, not elküldtünk.

Adverbial correlates are often omitted when they add no contrast:

Add ott when the main-clause place itself is contrastive or needs a visible anchor: Ott jelöld meg..., ahol... Omission is therefore governed by syntax and information structure, not by an English rule that Hungarian “always says then” or “always says there.”

Finite correlation versus compression

The two-clause pattern is explicit and natural in every register. Advanced (formal/academic) prose may compress the same descriptive material into a participle or noun phrase when the agent and time relation are recoverable.

The second version is not a correlative: ellenőrzött is a participle modifying dokumentumot. It is denser and more formal, while the finite first version foregrounds the checked material as a discourse topic. Compression is an information-packaging choice, not a more “correct” alternative.

Segmentation exercise

Analyze Azt küldtem vissza, amit véletlenül kétszer kihoztak.

• azt is the accusative main-clause demonstrative and focused object.
• küldtem vissza has definite first-person conjugation; focus places prefix vissza after the verb.
• the comma marks the subordinate-clause boundary.
• amit is the accusative relative object inside the second clause.
• kihoztak is third-person plural general: object relative amit selects the general conjugation inside its own relative clause. The relative operator also does not by itself trigger the prefix inversion associated with preverbal focus.

Common Mistakes

Key Takeaways

• Hungarian correlatives pair a main-clause demonstrative with a relative expression in the same semantic domain.
• Aki refers to people; ami refers to things, content, and situations.
• The two clauses assign case independently, so attól–akiben can be the correct pair for one referent.
• Ott–ahol, oda–ahová, and onnan–ahonnan preserve place versus direction.
• A recoverable correlate can be omitted, but object definiteness and verb conjugation remain.
• Finite correlatives foreground a relation; formal prose may instead compress it into a participial or nominal phrase.
