That-Clauses with Hogy in Hungarian

In Brief

Hungarian hogy introduces a clause that completes an idea, much like English “that”: Tudom, hogy jön means “I know that he/she is coming.” Write a comma before hogy, and normally keep hogy even where English can omit “that.” Statements usually use an ordinary indicative verb, while wishes, requests, and necessities often use the Hungarian imperative/subjunctive form.

Overview

A clause is a group of words with its own verb. A subordinate clause is a clause that forms part of a larger sentence instead of standing as the main message. In Tudom, hogy jön (“I know that he/she is coming”), tudom is the main clause and hogy jön supplies what is known. Hungarian hogy is therefore often the closest match for English “that.”

This is an A1 building block because it lets you combine simple messages: “Anna is at home” becomes the content of “I think,” “I know,” or “Péter said.” You will hear hogy constantly after verbs of knowing, thinking, saying, hearing, seeing, hoping, and wanting, as well as after expressions such as fontos (“important”) and jó (“good”).

English-speaking learners need to notice two habits that do not transfer directly. First, English often says “I think he is right” with no “that,” but Hungarian normally says Azt hiszem, hogy igaza van. Second, Hungarian punctuation requires a comma at the boundary before hogy. The beginner pattern is easy; the choice between azt and no azt, and between an ordinary verb and an imperative/subjunctive form, becomes clearer with practice.

How It Works

The basic sentence frame

The simplest frame is:

main clause + comma + hogy + content clause

Hungarian	English	Note
Tudom, hogy jön.	I know that he/she is coming.	The second clause says what I know.
Hallom, hogy esik az eső.	I hear that it is raining.	Hogy introduces what I hear.
Péter azt mondja, hogy fáradt.	Péter says that he is tired.	Azt points forward to the clause.

The clause after hogy has its own verb and may have its own subject, object, negation, and time expression. Hungarian has no grammatical gender in third-person pronouns or verb forms, so jön can mean “he is coming” or “she is coming”; context identifies the person.

The role of azt

Azt is the accusative form of az (“that”). The accusative marks the direct object—the person or thing directly affected or supplied by the verb. Before a hogy-clause, azt acts as a correlative: a pointing word in the main clause that looks ahead to the content that follows.

Compare:

Pattern	Example	Practical meaning
Verb + hogy-clause	Tudom, hogy igaz.	I know that it is true.
Azt + verb + hogy-clause	Azt mondta, hogy igaz.	He/She said that it is true.
Emphatic azt	Azt tudom, hogy ma dolgozik.	What I do know is that he/she is working today.

There is no single rule saying that every hogy-clause must have azt. Some common expressions naturally favor it, especially azt mondja (“says”), azt hiszi (“thinks/believes”), azt gondolja (“thinks”), azt akarja (“wants”), and azt reméli (“hopes”). With other verbs, particularly tud (“know”), the clause often appears directly: Tudom, hogy… Both Tudom, hogy… and Azt tudom, hogy… are possible, but the second can highlight or contrast what is known.

A useful beginner strategy is to learn whole frames rather than inventing a rule from the English translation:

• Tudom, hogy… — I know that…
• Nem tudom, hogy… — I do not know whether/what…
• Azt hiszem, hogy… — I think that…
• Azt mondja, hogy… — he/she says that…
• Remélem, hogy… — I hope that…
• Fontos, hogy… — it is important that…

The comma is part of the pattern

Standard Hungarian puts a comma before hogy because it separates the main clause from the subordinate clause:

• Örülök, hogy itt vagy. — I am glad that you are here.
• Szerintem igaz, hogy sokat dolgozik. — I think it is true that he/she works a lot.

Do not copy English punctuation. English usually has no comma in “I know that she is here,” but Hungarian does: Tudom, hogy itt van. If the hogy-clause comes first, a comma marks its end: Hogy mikor érkezik, nem tudom (“When he/she will arrive, I do not know”). This order is marked and is not the best beginner model, but it shows that the comma belongs at the clause boundary.

Facts: use the ordinary indicative form

The indicative is the ordinary verb form used to present information as a fact, belief, report, or perception. After verbs such as “know,” “say,” “think,” and “hear,” the verb after hogy is normally indicative:

• Tudom, hogy otthon van. — I know that he/she is at home.
• Azt mondta, hogy beteg. — He/She said that he/she was ill.
• Úgy gondolom, hogy ez jó ötlet. — I think that this is a good idea.

Hungarian does not mechanically shift the tense backward in reported speech as English often does. In Azt mondta, hogy beteg, the present form beteg (“is ill”; Hungarian omits “is” here in the present) can describe an illness that is still relevant. If the meaning is clearly earlier, Hungarian can mark that directly: Azt mondta, hogy beteg volt (“He/She said that he/she had been/was ill”). Choose the tense for the intended time, not merely because the reporting verb is past.

Wishes and necessity: the imperative/subjunctive form

Hungarian uses the same family of verb forms for commands and for many subordinate clauses expressing a desired, requested, necessary, or possible action. Grammars often call this the imperative-subjunctive; here, “subjunctive” simply means a verb form used for an action viewed as wanted or required rather than reported as a fact.

Meaning	Hungarian	English
fact or belief	Tudom, hogy tanulsz.	I know that you are studying.
importance or requirement	Fontos, hogy tanulj.	It is important that you study.
desired action	Azt akarom, hogy maradj.	I want you to stay.
request	Azt kérem, hogy várjon.	I ask you/him/her to wait.

For a beginner, the key contrast is tanulsz (“you are studying”) versus tanulj (“that you study / study!”), and maradsz (“you stay/are staying”) versus maradj (“that you stay / stay!”). The full formation of these verb forms is a separate topic; at this stage, recognize that meaning controls the choice.

Subjects can differ across the two clauses

The main clause and the hogy-clause may describe different people:

• Én tudom, hogy Anna dolgozik. — I know that Anna is working.
• Azt akarom, hogy te maradj. — I want you to stay.

Hungarian often omits personal pronouns because verb endings identify the person. In the second example, te can normally be omitted: Azt akarom, hogy maradj. English uses an object pronoun in “I want you to stay,” but Hungarian expresses “you” through the ending of maradj. Do not translate the English structure word for word as though you had to be an object before the second verb.

Word order inside the hogy-clause

A hogy-clause follows ordinary Hungarian word-order principles. Hungarian word order reflects topic and focus more strongly than English word order does. The element immediately before the finite verb often receives special focus:

• Tudom, hogy Anna ma dolgozik. — I know that Anna is working today. (neutral in a suitable context)
• Tudom, hogy ma Anna dolgozik. — I know that it is Anna who is working today.
• Tudom, hogy Anna ma nem dolgozik. — I know that Anna is not working today.

Beginners should use familiar neutral sentence patterns and avoid rearranging words just because English allows it. Hogy does not force the verb to the end; Hungarian is not using German-style subordinate-clause word order.

Examples in Context

Hungarian	English	Note
Tudom, hogy jön.	I know that he/she is coming.	Basic factual content
Látom, hogy fáradt vagy.	I can see that you are tired.	The second clause has its own subject, understood as “you.”
Hallottam, hogy új munkád van.	I heard that you have a new job.	Reported information
Azt mondta, hogy szép.	He/She said that it is beautiful.	Common azt mondta, hogy frame
Azt hiszem, hogy ez a busz jó.	I think this is the right bus.	English can omit “that”; Hungarian keeps hogy.
Remélem, hogy holnap ráérsz.	I hope you are free tomorrow.	Hope about a future situation
Örülök, hogy itt vagytok.	I am glad that you are here.	Addressed to more than one person
Igaz, hogy Budapesten laksz?	Is it true that you live in Budapest?	The whole sentence is a question.
Nem hiszem, hogy késő van.	I do not think it is late.	Negation is in the main clause.
Fontos, hogy tanulj.	It is important that you study.	Imperative/subjunctive after necessity
Azt akarom, hogy maradj.	I want you to stay.	Different understood subjects
Kérem, hogy írja alá itt.	Please sign here.	Formal request; literally “I ask that you sign here.”
Nem tudom, hogy otthon van-e.	I do not know whether he/she is at home.	Embedded yes/no question with -e
Megkérdezte, hogy mikor indulunk.	He/She asked when we were leaving.	Hogy can introduce an embedded question.

Common Mistakes

Dropping hogy because English drops “that”

• Wrong: Tudom jön.
• Right: Tudom, hogy jön.
• Why: English readily says “I know he/she is coming” without “that.” In this neutral Hungarian sentence, the two finite verbs need an explicit clause link: comma + hogy. You may encounter omission in some established or stylistically compressed patterns, but do not copy English omission automatically.

Copying English punctuation

• Wrong: Tudom hogy Anna itt van.
• Right: Tudom, hogy Anna itt van.
• Why: Standard Hungarian writes a comma before the subordinate conjunction hogy.

Inserting azt into every sentence

• Awkward as an automatic pattern: Azt tudom, hogy jön.
• Neutral: Tudom, hogy jön.
• Why: Azt tudom is grammatical, but it often suggests contrast: “What I do know is that…” Learn which expressions commonly use azt, instead of adding it mechanically to every hogy-clause.

Using an indicative form for a desired action

• Wrong: Azt akarom, hogy maradsz.
• Right: Azt akarom, hogy maradj.
• Why: Wanting someone to act normally requires the imperative/subjunctive form, not the ordinary statement form.

Forcing English tense shift in reported speech

• Misleading translation habit: changing every present form to past only because mondta means “said”
• Natural: Azt mondta, hogy fáradt. — He/She said that he/she was tired.
• Why: Hungarian chooses the subordinate tense according to the time meant. It has no automatic English-style “backshift” rule.

Putting the verb at the end

• Unnatural as a rule: rearranging every clause to imitate another European language’s subordinate order
• Right: Tudom, hogy Anna ma dolgozik.
• Why: Hogy does not send the Hungarian verb to the end. Normal Hungarian topic-and-focus rules still apply.

Usage Notes

In conversation, hogy is extremely frequent. It can introduce not only translated English “that”-clauses but also questions and quotations of content. For example, Nem tudom, hogy hol van means “I don’t know where he/she is.” Here English uses “where,” not “that,” but Hungarian commonly places hogy before the question word hol. In informal speech, speakers may sometimes leave it out: Nem tudom, hol van. Both patterns occur, while the version with hogy makes the clause boundary explicit.

Do not assume that hogy always has one fixed English translation. Depending on the construction, it may correspond to “that,” “whether,” an infinitive-like English structure, or no separate English word at all. Kérem, hogy várjon is naturally translated “Please wait,” not necessarily “I ask that you wait.” Translate the whole construction rather than replacing each word.

Hungarian may use úgy (“in such a way/so”) or azt in the main clause to anticipate what follows: Úgy látom, hogy esik (“It looks to me as if it is raining”) and Azt mondja, hogy esik (“He/She says that it is raining”). These pointing words belong to particular patterns and can also carry emphasis.

Beyond the Basics / Advanced Use

You do not need to master the following details at A1, but they explain forms you will meet later.

Embedded questions

After verbs of knowing, asking, and wondering, hogy can introduce an embedded question—a question placed inside a larger sentence. A question word may follow it: Megkérdezte, hogy hol lakom (“He/She asked where I live”). For an embedded yes/no question, Hungarian often adds the question particle -e to the finite verb: Nem tudom, hogy jön-e (“I don’t know whether he/she is coming”). The whole sentence need not be a direct question, so its punctuation follows the main sentence.

Purpose clauses

Hogy also introduces purpose: Azért jöttem, hogy segítsek (“I came in order to help”). The imperative/subjunctive segítsek presents the intended action. Purpose often has the anticipatory word azért (“for that purpose”) in the main clause. This use develops into the related B1 topic of purpose and result clauses.

Result and degree

In patterns such as annyira …, hogy … (“so … that …”), the hogy-clause states a result: Annyira fáradt volt, hogy elaludt (“He/She was so tired that he/she fell asleep”). Úgyhogy, written as one word, is a different conjunction meaning “so/as a result”: Esik, úgyhogy otthon maradunk (“It is raining, so we are staying home”). Do not confuse the one-word conjunction úgyhogy with ordinary úgy …, hogy … constructions.

Hogy repeated in speech

Colloquial Hungarian may use hogy while quoting or relaying someone’s words, and long sentences can contain more than one hogy-clause. Skilled writers may restructure such sentences to avoid repetition, but repetition is not automatically ungrammatical. As a learner, clarity is more important than avoiding every repeated hogy.

Mood reflects meaning, not simply the conjunction

Hogy itself does not automatically require a special mood. Compare Látom, hogy jössz (“I see that you are coming”) with Azt akarom, hogy gyere/gyere el (“I want you to come/come along”). The first reports a perceived fact, while the second describes a desired action. At higher levels, you will learn the full imperative/subjunctive system, including definite and indefinite verb forms and irregular verbs.

Practice Tips

1. Build sentence pairs. Start with two short statements—Anna dolgozik. Tudom.—and combine them: Tudom, hogy Anna dolgozik. Then change the main frame to Azt hiszem, hogy…, Hallottam, hogy…, or Remélem, hogy….
2. Learn frames aloud. Keep a short list of chunks such as Tudom, hogy…, Azt mondta, hogy…, and Fontos, hogy…. Completing these frames trains azt and the comma pattern more reliably than translating isolated English sentences.
3. Contrast fact and wish. Make pairs with the same verb: Tudom, hogy maradsz (“I know you are staying”) versus Azt akarom, hogy maradj (“I want you to stay”). Say what changes in meaning before checking the verb ending.
