Complement and Adverbial Clauses: Forms and Core Pattern

A subordinate clause can fill an argument position—“I know that she is here”—or specify time, cause, purpose, result, condition, or concession. Hungarian marks these relations with conjunctions such as hogy, amikor, mert, and ha, and often announces the clause in the main clause with a demonstrative correlate such as azt, akkor, or azért. Subordination does not create English or German word order inside the dependent clause: Hungarian topic and focus rules continue to operate there.

The complementizer hogy

Finite declarative content clauses normally begin with hogy “that.” They can function as the object selected by a verb of saying, knowing, noticing, or believing.

In the second example, accusative azt is a correlate: a demonstrative placeholder in the main clause that points forward to the hogy clause. Segment the structure as az-t mond-ta, hogy...: that-ACC say-PAST.3SG that.... Because the content is a definite clausal object, the main verb normally has definite conjugation (mondta, tudom, látjuk) whether or not azt is pronounced.

The correlate is not mechanically required after every verb. Tudom, hogy... is neutral and complete; Azt tudom, hogy... typically makes the known content contrastive (“What I do know is that...”); Azt mondta, hogy... is extremely common. Lexical government also decides the correlate’s case:

Számít valamire requires sublative arra; tart valamitől in this meaning requires ablative attól. A generic azt cannot replace a case selected by the matrix predicate.

Subject clauses

A finite clause can also supply what is evaluated, occurs, or matters. In a neutral evaluation, no overt subject correlate is necessary.

The hogy clause is what is important. Hungarian needs no dummy equivalent of English it. When the main clause explicitly contrasts or identifies the clausal subject, nominative az can point forward to it: Az a fontos, hogy időben elinduljunk “What matters is that we set off on time.”

Here nominative az is the grammatical subject of lepett meg and the following clause supplies its content. Case morphology and the predicate’s argument frame identify this relation; the correlate’s prominent position expresses information structure.

A compact map of adverbial clauses

The correlate is sometimes required by the selected frame, sometimes contrastive, and often optional. It belongs to the main clause; the conjunction belongs to the dependent clause.

Time and cause

Time clauses locate one event relative to another. The correlative pair akkor... amikor makes the matching points explicit, while neutral discourse often omits akkor.

Other common pairs include addig... amíg “until/as long as,” azután... miután “after,” and a clause with mielőtt “before.” Their finite verbs follow ordinary Hungarian tense choices rather than copying an English future auxiliary.

Cause normally uses mert or the somewhat more formal mivel. An overt azért foregrounds the reason relation.

This is not ezért “therefore.” In azért... mert, azért points forward to the cause clause; ezért normally points back to an already established cause and introduces a consequence.

Purpose and result: same hogy, different mood

Purpose describes an intended outcome. It commonly has azért or another goal-oriented correlate in the main clause and the imperative/subjunctive form in the hogy clause.

Elutaz-hass-unk contains the potential suffix and the imperative/subjunctive first-person plural ending. A negative purpose uses ne: hogy el ne késsünk “so that we do not arrive late.” Verbal-prefix order follows the subordinate clause’s own mood and information structure; see the imperative forms.

Result reports what actually follows from a degree or manner, so it normally uses the indicative.

Do not choose the mood from hogy alone. The matrix meaning determines whether the subordinate situation is asserted as a result, presented as intended, or required.

Condition and concession

Real or open conditions commonly use indicative verbs in both clauses:

Hypothetical and counterfactual conditions normally use Hungarian conditional morphology in both the ha clause and the result clause, unlike formal English if I were ... I would..., where only the result visibly contains would.

Concession says that the main event holds despite an expected obstacle. Factual bár/noha/jóllehet clauses generally use the indicative; jóllehet is (formal). Hypothetical még ha... is commonly combines with the conditional.

Punctuation and internal word order

Put a comma at the boundary between a main clause and a finite subordinate clause. This includes a comma before hogy, mert, amikor, ha, and bár when they introduce the second clause. If the dependent clause comes first, place the comma after it: Ha ráérsz, hívj fel. A correlate before the boundary does not remove the comma: Azt mondta, hogy...; Azért jött, hogy....

The complementizer stands at the left edge, but material after it is ordered by Hungarian discourse syntax:

The topic ezt a feladatot precedes focused Anna, and the prefix follows the verb in oldotta meg. Subordination does not push the finite verb to the end.

Segmentation exercise

Separate each correlate from its conjunction and identify the clause relation and mood.

1. Azt remélem, hogy hamarosan találkozunk. — az-t is an accusative object correlate; hogy introduces an indicative content clause.
2. Addig várunk, amíg befejezed. — addig is the main-clause time correlate; amíg introduces its temporal endpoint.
3. Azért halkította le a zenét, hogy a gyerek fel ne ébredjen. — azért announces purpose; hogy introduces negative imperative/subjunctive fel ne ébredjen.
4. Ha tudtam volna róla, szóltam volna. — ha introduces a past counterfactual; conditional auxiliary volna occurs in both clauses.

Common Mistakes

Key Takeaways

• Introduce finite declarative content with hogy; use a correlate whose case matches the main predicate when that correlate is needed.
• Do not insert an English dummy it before Hungarian subject clauses.
• Pair time, cause, purpose, result, condition, and concession clauses with their appropriate correlates and subordinators.
• Use imperative/subjunctive forms for intended or required outcomes, but normally indicative forms for asserted causes and results.
• Mark the clause boundary with a comma, while allowing ordinary Hungarian topic–focus order inside the subordinate clause.
