Erklären, abklären, aufklären and klären: four ways to make things clear
Erklären makes a meaning or reason understandable. Klären resolves an open question or uncertainty. Abklären checks or discusses a matter to establish clarity, often with another person. Aufklären can solve a case or inform someone about something they did not know. These are useful tendencies, not four sealed categories. You can explain a rule, clarify who is responsible, check an appointment with a colleague, or inform a customer about a risk. The object and the situation usually identify the intended meaning.
| Word | Core meaning | Typical context | Grammar |
|---|---|---|---|
| erklären | explain; also declare | Making ideas understandable | Inseparable er-. Weak: erklärt, erklärte, hat erklärt. Jemandem etwas erklären: recipient dative, explanation accusative; a why/how clause can supply the content. |
| abklären | check and clarify | Confirming details or an unresolved matter | Separable ab-: klärt ab, hat abgeklärt. Etwas abklären takes accusative; mit jemandem uses dative. You can also abklären, ob a proposal is possible. |
| aufklären | solve; inform or enlighten | Cases, misunderstandings and information | Separable auf-: klärt auf, hat aufgeklärt. Einen Fall aufklären; jemanden über etwas aufklären: person accusative, über + accusative. |
| klären | clarify; settle an uncertainty | Questions, responsibilities and causes | No separable prefix. Weak: klärt, klärte, hat geklärt. Etwas klären takes accusative; mit jemandem + dative can name a discussion partner. |
erklären
Meaning and usage: Use erklären for meanings, processes and reasons. The listener often already has a question and needs an explanation. The word also means declare in formal expressions, so it is not limited to teaching.
Grammar: Inseparable er-. Weak: erklärt, erklärte, hat erklärt. Jemandem etwas erklären: recipient dative, explanation accusative; a why/how clause can supply the content.
Kannst du mir diese Regel erklären?
Can you explain this rule to me?
abklären
Meaning and usage: Abklären emphasizes finding out or discussing what is still uncertain. It fits arrangements and practical questions; medical contexts can also use it for investigating an issue. It does not mean explain every time a topic is difficult.
Grammar: Separable ab-: klärt ab, hat abgeklärt. Etwas abklären takes accusative; mit jemandem uses dative. You can also abklären, ob a proposal is possible.
Ich kläre den Termin mit meiner Kollegin ab.
I will check the appointment with my colleague.
aufklären
Meaning and usage: A detective may aufklären a crime. A professional may aufklären a person about a risk. In the second construction, the person receives previously missing knowledge, rather than merely a definition.
Grammar: Separable auf-: klärt auf, hat aufgeklärt. Einen Fall aufklären; jemanden über etwas aufklären: person accusative, über + accusative.
Die Beraterin klärt uns über mögliche Risiken auf.
The adviser informs us about possible risks.
klären
Meaning and usage: Klären is the broad verb for making an unresolved situation clear. The subject might investigate, discuss or decide something. Sich klären means that a matter becomes clear.
Grammar: No separable prefix. Weak: klärt, klärte, hat geklärt. Etwas klären takes accusative; mit jemandem + dative can name a discussion partner.
Wir müssen klären, wer die Rechnung bezahlt.
We need to clarify who will pay the bill.
Overlap and context
Klären and abklären overlap substantially: either may fit checking a practical matter. Aufklären and klären can both resolve a misunderstanding. Choose familiar combinations instead of inventing a ranking from least to most thorough. Erklären describes understanding, while the other verbs often focus on removing uncertainty; context can combine both actions.
Common mistakes
- For explaining a grammar rule, jemanden aufklären is not the automatic substitute for jemandem etwas erklären.
- Keep the prefix at the end in a main clause: Ich kläre das ab. Erklären does not split.
Memory aid: Explain an idea; clarify an issue; check a detail; inform a person or solve a case. These prompts guide common uses, but the full phrase decides.

Sagen, erzählen, sprechen or reden: choosing the right German verb
Sagen focuses on what someone says; erzählen commonly presents an account, story or experience; sprechen and reden focus on speaking or talking. Sprechen is the usual choice for a language ability. Sprechen and reden overlap widely in conversations, so the objects and context often matter more than the English translation.
| Word | Core meaning | Typical context | Grammar |
|---|---|---|---|
| sagen | say; tell a fact | a statement or short message | jemandem etwas sagen |
| erzählen | tell; recount | an experience, story or information | jemandem etwas erzählen |
| sprechen | speak; talk | languages; conversations | mit + dative; über + accusative |
| reden | talk; speak | conversation; discussing a subject | mit + dative; über + accusative |
sagen
Meaning and usage: Choose sagen to report a statement, give information or reproduce someone’s words. It does not require a long conversation. A dass-clause can supply the information instead of a noun object.
Grammar: Not separable; sagt–sagte–hat gesagt. The listener is dative and the information is accusative or a clause.
Kannst du mir sagen, wann der Kurs beginnt?
Can you tell me when the course starts?
erzählen
Meaning and usage: Erzählen suits recounting what happened and telling stories. It also means communicating personal information. A factual report can therefore be erzählt: it need not be fictional or entertaining.
Grammar: Inseparable er-; erzählt–erzählte–hat erzählt. Jemandem etwas erzählen; von + dative or über + accusative can introduce the subject.
Sie erzählt ihrem Bruder von ihrem ersten Arbeitstag.
She tells her brother about her first day at work.
sprechen
Meaning and usage: Sprechen describes producing speech, speaking a language, addressing someone or discussing a topic. It is natural in both everyday and formal settings; it is not exclusively formal.
Grammar: Not separable; spricht–sprach–hat gesprochen. Eine Sprache sprechen; mit jemandem sprechen; über etwas sprechen.
Ich spreche Deutsch, aber mit meiner Schwester spreche ich Englisch.
I speak German, but I speak English with my sister.
reden
Meaning and usage: Reden commonly describes talking, especially the activity of a conversation. It can also describe giving a speech. It is often interchangeable with sprechen when discussing an issue.
Grammar: Not separable; redet–redete–hat geredet. Mit jemandem reden; über etwas reden.
Wir haben lange über die neue Wohnung geredet.
We talked about the new apartment for a long time.
Overlap and context
Ich sage dir etwas identifies a message; ich rede mit dir identifies an interaction. Ich erzähle dir etwas may describe one short piece of information as well as a longer account. Avoid treating “speak is formal, talk is informal” as a fixed German rule. A doctor can reden, and friends can sprechen.
Common mistakes
- Do not translate “tell me” automatically as erzähl mich: the listener is mir.
- For ordinary language ability, say Ich spreche Deutsch, rather than using reden as your default.
- Avoid sprechen über dem Problem: über a topic takes the accusative.
Memory aid: Message: sagen. Account: erzählen. Speech or conversation: sprechen/reden.

Fragen vs. befragen vs. nachfragen vs. hinterfragen
Fragen is the general verb for asking. Befragen focuses on questioning a person, often about a particular topic. Nachfragen means asking for more information or following up. Hinterfragen means examining the assumptions or reasons behind something critically. A request for an address and a challenge to a policy's assumptions are different kinds of questioning.
| Word | Core meaning | Typical context | Grammar |
|---|---|---|---|
| fragen | ask a question | everyday questions and requests for information | accusative person; nach + dative; hat gefragt |
| befragen | question or interview someone | surveys, interviews, investigations | inseparable; accusative person; zu/nach + dative |
| nachfragen | follow up; ask again or seek details | unclear answers and information checks | separable; bei + dative; hat nachgefragt |
| hinterfragen | critically examine underlying assumptions | arguments, rules and accepted explanations | inseparable; accusative object; hat hinterfragt |
fragen
Meaning and usage: Fragen covers ordinary information-seeking. You can name the person, the requested information, or a question clause. It does not automatically mean conducting an interview or doubting what someone says.
Grammar: Regular, nonseparable: fragt, fragte, hat gefragt. The person is accusative: jemanden fragen. For requested information, use nach + dative; a clause can follow ob, wie or warum.
Ich frage den Fahrer nach der nächsten Haltestelle.
I ask the driver about the next stop.
befragen
Meaning and usage: Befragen presents the person as the focus of questioning. It often suggests a planned or detailed set of questions, but it is not restricted to police interrogations. A researcher can befragen participants about their experience.
Grammar: Regular and inseparable: befragt, befragte, hat befragt. Use an accusative person. A topic can follow zu + dative, nach + dative or über + accusative, depending on the wording.
Die Forscherin befragt die Teilnehmenden zu ihren Lerngewohnheiten.
The researcher questions the participants about their learning habits.
nachfragen
Meaning and usage: Nachfragen is useful when an answer is missing, unclear or needs checking. It can also mean making an initial inquiry, so it does not always require that you personally asked once before.
Grammar: Regular and separable: fragt nach, fragte nach, hat nachgefragt. Say bei jemandem nachfragen, with dative. A topic can be expressed with nach + dative or a question clause.
Ich frage morgen im Büro nach, ob der Termin bestätigt ist.
I will check with the office tomorrow whether the appointment is confirmed.
hinterfragen
Meaning and usage: Hinterfragen goes beyond obtaining an answer: it explores whether the foundations or reasoning hold up. It does not necessarily reject the claim. You may question a rule and conclude that it is justified.
Grammar: Regular and inseparable: hinterfragt, hinterfragte, hat hinterfragt. Usually takes an accusative object such as eine Annahme or eine Entscheidung. Do not split hinter- from the verb.
Im Seminar hinterfragen wir die Annahmen des Modells.
In the seminar, we critically examine the model's assumptions.
Overlap and context
Fragen and befragen can describe the same interaction, with befragen placing more emphasis on questioning the person. Nachfragen may be neutral and practical; hinterfragen emphasizes critical examination. These are useful tendencies rather than four completely separate boxes.
Common mistakes
- Use Ich frage ihn, not Ich frage ihm; the person with fragen is accusative.
- Do not use hinterfragen for every polite follow-up question.
- Only nachfragen separates here: Ich frage nach, but Ich hinterfrage die Regel.
Memory aid: Fragen asks; befragen questions someone; nachfragen follows up; hinterfragen looks behind the claim.

Antworten, beantworten, erwidern and reagieren: how to respond
Antworten means answer someone or respond to a question. Beantworten takes the question, message or similar item directly as its object. Erwidern can mean reply or return a gesture or feeling. Reagieren covers responding more broadly, including responses without words.
| Word | Core meaning | Typical context | Grammar |
|---|---|---|---|
| antworten | answer; reply | A person or question receiving a response | Regular, inseparable: antwortet, antwortete, hat geantwortet. |
| beantworten | answer something | Questions, letters and requests | Regular, inseparable: beantwortet, beantwortete, hat beantwortet. |
| erwidern | reply; reciprocate | Quoted replies or returned gestures | Regular, inseparable: erwidert, erwiderte, hat erwidert. |
| reagieren | react; respond | Behavior, feelings and physical responses | Regular, inseparable: reagiert, reagierte, hat reagiert. |
antworten
Meaning and usage: Antworten is an everyday choice for a spoken or written answer. The recipient is commonly dative, while the question or message can follow auf. You do not have to identify both: Sie antwortet is a complete statement. In some contexts the verb also describes a nonverbal response, so spoken words are typical rather than obligatory.
Grammar: Regular, inseparable: antwortet, antwortete, hat geantwortet. Jemandem antworten: dative; auf eine Frage antworten: auf + accusative.
Ich habe dem Vermieter gestern geantwortet.
I replied to the landlord yesterday.
beantworten
Meaning and usage: Beantworten places the thing answered at the center of the sentence. It suits questions, messages and letters. A person is not normally its direct object in this sense: you answer their question, not “answer them” using the same English structure. The be- prefix changes the object pattern as well as the shape of the verb.
Grammar: Regular, inseparable: beantwortet, beantwortete, hat beantwortet. Eine Frage/eine E-Mail beantworten: direct accusative object.
Die Trainerin beantwortet jede Frage am Ende.
The trainer answers every question at the end.
erwidern
Meaning and usage: Erwidern can introduce a reply in a conversation, including a counterargument. It is also used when someone returns a smile, greeting, visit or affection. This second meaning makes it broader than a simple answer verb. It can sound more written or deliberate than antworten in dialogue narration, without always implying disagreement.
Grammar: Regular, inseparable: erwidert, erwiderte, hat erwidert. A reply may be quoted or expressed with a clause; einen Gruß/einen Blick erwidern takes accusative.
Mara erwiderte das Lächeln des Kindes.
Mara returned the child’s smile.
reagieren
Meaning and usage: Reagieren describes the response to a stimulus, statement or event. That response may be an answer, a change in behavior or a bodily reaction. Use it when the form of the response matters more than answering a particular question. It is common with promptly, calmly or angrily, because those describe how someone reacts.
Grammar: Regular, inseparable: reagiert, reagierte, hat reagiert. Auf etwas reagieren: auf + accusative; mit etwas reagieren: mit + dative.
Das Team reagierte ruhig auf die Kritik.
The team reacted calmly to the criticism.
Overlap and context
Answering an email is also a way of reacting to it. However, reagieren does not promise that its questions were answered. Erwidern and antworten overlap for verbal replies; reciprocating a smile is a distinct, particularly useful erwidern context.
Common mistakes
- Say Ich antworte dem Kunden, but Ich beantworte die Frage des Kunden. The direct object changes.
- Use auf die Nachricht reagieren, rather than directly treating die Nachricht as an accusative object after reagieren.
- Erwidern does not necessarily mean contradict. Returning a greeting is an ordinary nonargumentative use.
Memory aid: Antworten follows the person; beantworten handles the question; reagieren describes the response; erwidern can give something back.

Sprechen vs. besprechen vs. aussprechen vs. versprechen
Sprechen means speaking. Besprechen means discussing something with another person. Aussprechen can mean pronouncing a word or expressing something explicitly. Versprechen means promising; sich versprechen means making a slip of the tongue. The shared root is useful for learning the forms, but each complete verb needs its own sentence pattern.
| Word | Core meaning | Typical context | Grammar |
|---|---|---|---|
| sprechen | speak; talk | languages and conversations | strong; mit + dative, über + accusative |
| besprechen | discuss something | plans, problems and arrangements | inseparable; accusative topic; mit + dative |
| aussprechen | pronounce; express explicitly | words, wishes and stated positions | separable; accusative object; hat ausgesprochen |
| versprechen | promise; misspeak reflexively | commitments and slips of the tongue | inseparable; dative recipient; reflexive mich for misspeaking |
sprechen
Meaning and usage: Sprechen names the act of speaking, a language you speak, or a conversation. For a conversation topic, German commonly uses über. It is broader than discussing a specific issue to reach a decision.
Grammar: Strong, nonseparable: spricht, sprach, hat gesprochen. Say eine Sprache sprechen, mit jemandem sprechen (dative), and über etwas sprechen (accusative).
Ich spreche mit meiner Kollegin über den neuen Stundenplan.
I am talking to my colleague about the new timetable.
besprechen
Meaning and usage: Besprechen makes the issue the direct object of the discussion. It often suits practical matters requiring shared attention. The reflexive sich besprechen means consulting or discussing with one another.
Grammar: Strong and inseparable: bespricht, besprach, hat besprochen. Use an accusative topic: den Plan besprechen. Add mit + dative for the other person. The usual direct-object construction does not require über.
Wir besprechen die Aufgabenverteilung nach der Pause.
We will discuss the allocation of tasks after the break.
aussprechen
Meaning and usage: Aussprechen refers to articulating a word, but also to putting a thought, wish or sympathy into words. Sich für or gegen etwas aussprechen means declaring support or opposition. It is not limited to pronunciation practice.
Grammar: Strong and separable: spricht aus, sprach aus, hat ausgesprochen. Usually takes an accusative object. For a position, sich aussprechen für/gegen + accusative is a common reflexive construction; nonreflexive wording is also possible in this sense.
Kannst du diesen Ortsnamen langsam aussprechen?
Can you pronounce this place name slowly?
versprechen
Meaning and usage: Versprechen commits the speaker to something. Add a reflexive pronoun in sich versprechen and the meaning changes to saying something unintended. Another construction, sich etwas von etwas versprechen, describes hoping for a benefit.
Grammar: Strong and inseparable: verspricht, versprach, hat versprochen. Promise someone (dative) something (accusative), a dass-clause or an infinitive with zu. In the slip-of-the-tongue sense: ich verspreche mich.
Ich verspreche dir, die Unterlagen heute zu schicken.
I promise you that I will send the documents today.
Bei der Zahl habe ich mich versprochen.
I misspoke when I said the number.
Overlap and context
Sprechen über and besprechen can describe the same discussion. Besprechen packages the topic as a direct object. Aussprechen describes what you articulate or state; versprechen adds commitment. Reflexive pronouns sometimes change the meaning substantially, so read the whole construction.
Common mistakes
- Say Wir besprechen den Plan, rather than automatically inserting über after besprechen.
- Do not confuse hat ausgesprochen with hat versprochen.
- Sich versprechen means misspeaking, not promising something to oneself.
Memory aid: Speak generally, discuss the issue, say it out loud, then promise an action.
Try it

besprechen
Besprechen takes the discussed topic directly as an accusative object.

Bedeuten, heißen and meinen: three ways English uses mean
Bedeuten asks about meaning or significance. Heißen tells you what someone or something is called and can also express what a phrase means. Meinen concerns a person's opinion or intended message. English 'mean' covers these uses, so translate the function of the sentence.
| Word | Core meaning | Typical context | Grammar |
|---|---|---|---|
| bedeuten | Have a meaning; signify | A word, symbol, consequence or importance | No separable prefix; bedeutet; hat bedeutet |
| heißen | Be called; mean | Names, labels, wording and equivalent expressions | No separable prefix; heißt; hieß; hat geheißen |
| meinen | Mean or intend; think | A speaker's point, intention or opinion | No separable prefix; etwas meinen; hat gemeint |
bedeuten
Meaning and usage: Use it to explain what a sign or word conveys. It also describes consequences or importance. A person's presence can mean a great deal to you, without any linguistic definition being involved.
Grammar: The meaning can appear as a phrase or a dass-clause. Importance often uses a dative person: das bedeutet mir viel. The prefix be- stays attached; the perfect is hat bedeutet.
Was bedeutet dieses Symbol auf dem Display?
What does this symbol on the display mean?
Deine Hilfe bedeutet mir viel.
Your help means a lot to me.
heißen
Meaning and usage: For a name, ask Wie heißt du? For a German label or translation, ask Wie heißt das auf Deutsch? Heißen can also overlap with bedeuten when you ask what wording means, rather than simply naming an object.
Grammar: Names and labels act as complements, not as something the subject deliberately names. Forms: heißt, hieß, hat geheißen. In das heißt, the phrase introduces an explanation: 'that is' or 'in other words'.
Wie heißt dieses Werkzeug auf Deutsch?
What is this tool called in German?
Der Laden ist geschlossen, das heißt, wir müssen morgen wiederkommen.
The shop is closed; that means we'll have to come back tomorrow.
meinen
Meaning and usage: Ask Was meinst du? when you want the other person's point or opinion. With a statement or clause, it can mean thinking something is true. With an adverb such as ironisch, it concerns the intention behind the words.
Grammar: An accusative object is possible: das meine ich. Opinions can use a dass-clause or another reported statement. Forms: meint, meinte, hat gemeint.
Ich habe das nicht ironisch gemeint.
I didn't mean that ironically.
Ich meine, dass wir früher losfahren sollten.
I think we should leave earlier.
Overlap and context
Was heißt das? and Was bedeutet das? can both ask for an explanation. Was meinst du damit? shifts attention to the speaker's intended point. A useful distinction can exist even when more than one verb fits.
Common mistakes
- For somebody's name, ask Wie heißt du?, rather than Was bedeutest du?
- Do not replace meinen with bedeuten when explaining your own intended message.
Memory aid: Bedeuten: the meaning. Heißen: the name or wording. Meinen: the person's point.
