Denken, nachdenken, überdenken and bedenken: thinking precisely
Denken is the general verb think. Nachdenken emphasizes reflecting on something. Überdenken means consider something carefully, often again. Bedenken can mean consider or take something into account. The meanings overlap, but their common grammatical constructions differ.
| Word | Core meaning | Typical context | Grammar |
|---|---|---|---|
| denken | think; have in mind | Thoughts, beliefs and remembering someone | Irregular, inseparable: denkt, dachte, hat gedacht. |
| nachdenken | reflect; think about | Taking time over a question or problem | Separable: denkt nach, dachte nach, hat nachgedacht. |
| überdenken | consider carefully; reconsider | Plans, decisions and positions | Inseparable: überdenkt, überdachte, hat überdacht. |
| bedenken | consider; take into account | Relevant circumstances before acting | Inseparable: bedenkt, bedachte, hat bedacht. |
denken
Meaning and usage: Denken covers mental activity and expressing a belief. Denken an places a person or thing in your thoughts; denken, dass introduces what you believe. It can also express your opinion about a topic. It is the broadest verb here, so the accompanying phrase does much of the work.
Grammar: Irregular, inseparable: denkt, dachte, hat gedacht. An + accusative for having something in mind; a dass-clause for a belief.
Ich denke oft an meine erste Lehrerin.
I often think about my first teacher.
nachdenken
Meaning and usage: Nachdenken suggests spending mental effort on a matter. It need not produce a decision or a changed opinion. The topic normally follows über. This verb is useful when you want time to reflect rather than immediately agree. It does not itself mean think again; that needs the surrounding context or noch einmal.
Grammar: Separable: denkt nach, dachte nach, hat nachgedacht. Über + accusative; zu-infinitive nachzudenken.
Ich denke noch über deinen Vorschlag nach.
I am still thinking about your proposal.
überdenken
Meaning and usage: Überdenken makes a plan, decision or situation the direct object of careful consideration. It is common when reviewing a position, but changing it is not guaranteed. You can thoroughly überdenken something and keep the original decision. This is a useful way to distinguish reconsidering from actually revising.
Grammar: Inseparable: überdenkt, überdachte, hat überdacht. Direct accusative object; zu-infinitive zu überdenken.
Wir müssen den Zeitplan noch einmal überdenken.
We need to reconsider the schedule.
bedenken
Meaning and usage: Bedenken often draws attention to a fact that should influence a decision. It also means think a matter through more generally. In Bedenke, dass … the speaker asks you to bear a circumstance in mind. A separate meaning concerns giving someone something; this lesson focuses on mental consideration.
Grammar: Inseparable: bedenkt, bedachte, hat bedacht. Accusative object or dass-clause; etwas zu bedenken geben is an established expression.
Bedenke bitte, dass der Zug sonntags später fährt.
Please bear in mind that the train runs later on Sundays.
Overlap and context
Nachdenken, überdenken and bedenken can all describe serious consideration. A useful practical distinction is the sentence frame: über den Plan nachdenken versus den Plan überdenken. Do not turn that grammatical difference into an absolute difference in the depth of thought.
Common mistakes
- Write Ich denke darüber nach with the separated nach at the end of a simple main clause.
- Do not separate überdenken: Ich überdenke den Plan, not Ich denke den Plan über.
- Bedenken does not mean regret. A person may take a risk into account without feeling sorry about it.
Memory aid: An keeps someone in mind; über … nach gives a topic for reflection; a direct object suits überdenken or bedenken.

nach
The separable verb nachdenken takes über as the topic preposition; its prefix moves to the clause end.

glauben vs. meinen vs. vermuten: meanings and usage in German
Glauben expresses belief or what you think is true. Meinen often gives an opinion, but also means what you intend or refer to when speaking. Vermuten presents a supposition, often prompted by clues. These verbs overlap in statements such as Ich glaube/meine/vermute, dass …; they do not form a reliable scale of exact certainty percentages.
| Word | Core meaning | Typical context | Grammar |
|---|---|---|---|
| glauben | believe or think true | a statement, person or belief | jemandem glauben; an + accusative |
| meinen | hold an opinion; mean | a view or intended reference | etwas/jemanden meinen; dass-clause |
| vermuten | suppose or suspect | an explanation based on clues | etwas vermuten; dass-clause |
glauben
Meaning and usage: Use glauben when you accept a statement or think it is likely. It can be a tentative conversational opinion or a firmly held belief. Glauben an expresses belief in existence or confidence in someone, rather than simply believing what that person says.
Grammar: Weak: glaubte, hat geglaubt. Believe a person: jemandem glauben, dative. Believe a claim: etwas glauben, accusative. Glauben an takes accusative; a dass-clause places the conjugated verb last.
Ich glaube dir, aber ich möchte den Termin prüfen.
I believe you, but I would like to check the appointment.
Sie glaubt an ihre Idee.
She believes in her idea.
meinen
Meaning and usage: Use meinen to express your view or clarify your intended meaning. Was meinst du? can ask for an opinion. Wen meinst du? asks which person you refer to. This reference meaning cannot simply be replaced with believing.
Grammar: Weak: meinte, hat gemeint. A referenced person or thing is accusative. Mit + dative can introduce the wording being explained: Was meinst du mit diesem Ausdruck? Opinion clauses can use dass.
Ich meine die blaue Tasche, nicht die schwarze.
I mean the blue bag, not the black one.
Ich meine, dass wir früher anfangen sollten.
I think we should start earlier.
vermuten
Meaning and usage: Use vermuten when you propose an explanation without presenting it as established fact. A clue may support the guess, but the verb does not promise that the guess is well researched or correct.
Grammar: Inseparable ver-; vermutete, hat vermutet. An accusative object can name the suspected cause; a dass-clause can state the full supposition.
Ich vermute, dass der Zug verspätet ist.
I suspect that the train is delayed.
Die Technikerin vermutet einen Fehler im Kabel.
The technician suspects a fault in the cable.
Overlap and context
For a prediction, all three verbs may be possible. Vermuten makes the supposition explicit; glauben is a broad everyday choice; meinen often foregrounds the speaker’s view. Tone, evidence and situation affect certainty. In Ich meine den Eingang links, however, meinen identifies the intended entrance. That sentence is about reference rather than belief or guessing.
Common mistakes
- Distinguish Ich glaube dir from Ich glaube an dich: believing your statement differs from having confidence in you.
- Do not translate every English mean as glauben.
- Avoid claiming vermuten always means weak belief or glauben always implies religious faith.
Memory aid: Ask what you are doing: accepting a claim, giving or clarifying a view, or proposing an explanation. Let the complete sentence guide glauben, meinen or vermuten.
Try it
Someone asks which folder you mean. Complete: Ich ___ den Ordner auf dem Tisch.

meine
The sentence identifies your intended reference. Glaube and vermute do not express that ordinary meaning in this construction.

Fallen, gefallen, auffallen and einfallen: four different meanings
Fallen means fall; gefallen means appeal to or please someone; auffallen means stand out or be noticed; einfallen can mean occur to someone. For the last three everyday senses, the person experiencing the reaction is dative: mir gefällt …, mir fällt … auf and mir fällt … ein.
| Word | Core meaning | Typical context | Grammar |
|---|---|---|---|
| fallen | fall | an object dropping | fällt–fiel–ist gefallen |
| gefallen | appeal to; be liked | a person liking something | dative experiencer; hat gefallen |
| auffallen | stand out; be noticed | a conspicuous detail | fällt … auf; ist aufgefallen |
| einfallen | come to mind | an idea or remembered name | fällt … ein; ist eingefallen |
fallen
Meaning and usage: Fallen describes dropping or losing your balance. Prices and temperatures can also fallen. Its participle is gefallen, which has the same spelling as the separate infinitive meaning “please”. The auxiliary and sentence structure help you identify the intended verb.
Grammar: Not separable; fällt–fiel–ist gefallen. No accusative object in the basic falling sense. A destination can follow a preposition.
Der Schlüssel ist hinter den Schrank gefallen.
The key fell behind the cupboard.
gefallen
Meaning and usage: Gefallen expresses a positive reaction: the thing you like is the subject. It can also concern whether a situation seems satisfactory. In Das gefällt mir nicht, you are not the grammatical subject even though you experience the reaction.
Grammar: Inseparable; gefällt–gefiel–hat gefallen. Jemandem gefallen requires a dative person. Singular or plural verb agreement follows the thing liked.
Die Bilder gefallen mir, aber die Musik gefällt mir nicht.
I like the pictures, but I do not like the music.
auffallen
Meaning and usage: Auffallen describes attracting attention or becoming noticeable. It can stand alone for standing out, or name the person who notices something. It does not by itself say that the detail is attractive or approved of.
Grammar: Separable: fällt auf–fiel auf–ist aufgefallen. Jemandem auffallen uses the dative. A dass-clause can supply the noticeable fact.
Mir fällt auf, dass der Laden heute früher schließt.
I notice that the shop closes earlier today.
einfallen
Meaning and usage: Einfallen describes an idea, answer or memory coming to mind. The idea or name is the subject; the person remembering it is dative. Other senses include collapsing inward, invading and arriving suddenly, so not every einfallen concerns thinking.
Grammar: Separable: fällt ein–fiel ein–ist eingefallen. Jemandem etwas einfallen: etwas is the nominative subject, not an accusative object.
Mir fällt der Name unseres neuen Nachbarn nicht ein.
I cannot remember our new neighbour’s name.
Overlap and context
Das Kleid gefällt mir means I like the dress; das Kleid fällt mir auf means I notice it. Neither implies the other. Compare Die Vase ist gefallen, a fall, with die Vase hat mir gefallen, a positive reaction. Einfallen is not a deliberate act of invention; it presents the idea arriving in your mind.
Common mistakes
- Avoid Ich gefalle die Bilder for “I like the pictures”. Use Die Bilder gefallen mir.
- Avoid Mir habe eine Idee eingefallen. Use Mir ist eine Idee eingefallen.
- The separate verb gefallen has no extra ge- in its participle.
Memory aid: Fall down; appeal to me; stand out to me; come into my mind. Learn each with a complete mini-sentence.

hat
Here gefallen means appeal to someone, not fall.

Weisen, beweisen, nachweisen and hinweisen: pointing is not proving
Weisen points or directs, often in a more formal style. Beweisen proves or demonstrates something. Nachweisen establishes something with evidence, documentation or detection. Hinweisen directs attention to something or indicates it. Beweisen and nachweisen overlap; neither is universally stronger. A document may prove a qualification, a test may detect a substance, and a sign may point out a danger without proving that a particular accident will occur.
| Word | Core meaning | Typical context | Grammar |
|---|---|---|---|
| weisen | point; show a direction | Signs, directions and formal expressions | Strong: weist, wies, hat gewiesen; no separable prefix. Jemandem den Weg weisen has dative person and accusative route. Auf + accusative or a directional phrase can identify the direction. |
| beweisen | prove; demonstrate | Claims and qualities shown by evidence | Inseparable be-. Strong: beweist, bewies, hat bewiesen. Etwas beweisen takes accusative; jemandem etwas beweisen adds a dative recipient. A dass clause can supply the claim. |
| nachweisen | establish; document; detect | Qualifications, records and test results | Separable nach-: weist nach, wies nach, hat nachgewiesen. Etwas nachweisen takes accusative; jemandem etwas nachweisen can add dative. |
| hinweisen | point out; indicate | Attention and signs of a possible conclusion | Separable hin-: weist hin, wies hin, hat hingewiesen. Auf etwas hinweisen takes auf + accusative; jemanden auf etwas hinweisen adds an accusative person. |
weisen
Meaning and usage: Weisen can show where to go or direct someone somewhere. Many everyday speakers would use zeigen for showing a route, while jemandem den Weg weisen is a well-established expression. It is not the ordinary verb for proving a factual claim.
Grammar: Strong: weist, wies, hat gewiesen; no separable prefix. Jemandem den Weg weisen has dative person and accusative route. Auf + accusative or a directional phrase can identify the direction.
Ein Schild weist auf den Ausgang.
A sign points to the exit.
beweisen
Meaning and usage: Beweisen supports the truth of a claim or shows a quality such as patience or courage. Sich beweisen means demonstrate your ability. Evidence can come from argument, observation or documents; the verb does not require a courtroom or mathematics problem.
Grammar: Inseparable be-. Strong: beweist, bewies, hat bewiesen. Etwas beweisen takes accusative; jemandem etwas beweisen adds a dative recipient. A dass clause can supply the claim.
Diese Aufnahme beweist, dass sie dort war.
This recording proves that she was there.
nachweisen
Meaning and usage: Nachweisen often emphasizes an identifiable basis for a fact: records documenting employment, a test detecting a substance, or evidence establishing an event. It can replace beweisen in some contexts, but it also has these characteristic documentation and detection uses.
Grammar: Separable nach-: weist nach, wies nach, hat nachgewiesen. Etwas nachweisen takes accusative; jemandem etwas nachweisen can add dative.
Sie muss ihre Berufserfahrung nachweisen.
She must provide evidence of her work experience.
hinweisen
Meaning and usage: Hinweisen may draw someone’s attention to a rule or risk. With a sign or finding as subject, it may indicate something. Evidence that auf etwas hinweist need not settle the matter as a proof would.
Grammar: Separable hin-: weist hin, wies hin, hat hingewiesen. Auf etwas hinweisen takes auf + accusative; jemanden auf etwas hinweisen adds an accusative person.
Die E-Mail weist uns auf eine neue Frist hin.
The email draws our attention to a new deadline.
Overlap and context
Beweisen and nachweisen can both establish a fact conclusively. Treat documentation and detection as helpful contexts for nachweisen, not a rigid ban on using beweisen. Hinweisen can be weaker evidence, but its communication sense may simply mean point something out. A source’s actual evidence decides how certain a conclusion is.
Common mistakes
- Do not confuse weist from weisen with weiß from wissen.
- Use auf eine Änderung hinweisen, not eine Änderung hinweisen without auf.
Memory aid: A sign points; evidence proves; a record documents; a notice points something out. Match the type of information to the complete phrase.

Complete: Die Lehrerin weist uns ___ den Fehler hin.

auf
The pattern is jemanden auf etwas hinweisen, with auf + accusative.

testen vs. prüfen vs. überprüfen vs. kontrollieren: meanings and usage in German
Testen puts something through a test or trial. Prüfen examines it against requirements or checks whether it is correct. Überprüfen commonly verifies or reviews something, sometimes again. Kontrollieren means checking or monitoring, and can also mean having control. These verbs overlap substantially; choose the task and collocation rather than assigning each an exclusive English translation.
| Word | Core meaning | Typical context | Grammar |
|---|---|---|---|
| testen | test or try out | performance and suitability | testete; hat getestet |
| prüfen | examine or assess | requirements, documents or candidates | prüfte; hat geprüft |
| überprüfen | verify or review | accuracy, condition or decisions | inseparable über-; hat überprüft |
| kontrollieren | check, monitor or control | tickets, work or a vehicle | -ieren participle: kontrolliert |
testen
Meaning and usage: Use testen when a test procedure or practical trial is central. You can test a product, a material or a person’s ability. Ausprobieren may be an appropriate translation when you try something to see whether it works for you.
Grammar: Weak verb: testete, hat getestet. The tested person or thing is accusative. Auf + accusative can name a tested property: etwas auf seine Festigkeit testen.
Wir testen die neue App auf zwei Geräten.
We are testing the new app on two devices.
prüfen
Meaning and usage: Use prüfen when you examine suitability, correctness or compliance with requirements. It also describes an examiner assessing a candidate. Checking a document need not involve a formal exam, despite the related noun Prüfung.
Grammar: Weak: prüfte, hat geprüft. The examined object is accusative. An ob-clause can state the question under investigation and places its conjugated verb at the end.
Bitte prüfen Sie, ob die Angaben vollständig sind.
Please check whether the information is complete.
überprüfen
Meaning and usage: Use überprüfen to check validity, functioning or correctness, or to reconsider a position or decision. It often suggests a verification or review, but an earlier explicit prüfen action need not have been mentioned.
Grammar: Inseparable über- in this verb: überprüfte, hat überprüft; no ge-. The object is accusative. A question or dass-clause can supply the content being verified.
Ich überprüfe die Adresse vor dem Versand.
I am checking the address before shipping.
kontrollieren
Meaning and usage: Use kontrollieren for checks and supervision: inspecting tickets or monitoring work. It can also mean commanding or keeping control of something. Therefore, the claim that German kontrollieren never means English control is incorrect.
Grammar: Weak -ieren verb: kontrollierte, hat kontrolliert, without ge-. The checked or controlled object is accusative. Auf + accusative can specify what is checked for.
Die Mitarbeiterin kontrolliert die Fahrkarten.
The employee is checking the tickets.
Der Fahrer konnte das Auto noch kontrollieren.
The driver could still control the car.
Overlap and context
Eine Rechnung prüfen, überprüfen or kontrollieren may all describe checking an invoice, with different emphasis. Testen is especially natural when trying its performance, rather than simply confirming a number. Überprüfen does not impose a universal rule that every action happens twice. Give your reader the exact task—accuracy, trial, compliance or supervision—when a bare verb leaves room for several interpretations.
Common mistakes
- Do not separate überprüfen as Ich prüfe über.
- Use getestet but kontrolliert: -ieren verbs do not add ge-.
- Do not limit kontrollieren to inspection; management or physical control senses are documented.
Memory aid: A trial tests; an examination assesses; verification checks a claim; monitoring keeps watch. These are emphasis cues, not four sealed categories that ban familiar overlapping uses.
Try it
Before posting a parcel, you confirm the address. Give one suitable verb: Ich ___ die Adresse.
Show the answer
überprüfe; prüfe or kontrolliere can also fit
The task is verification. Several verbs are natural here; the sentence does not provide a unique lexical answer. Teste would need a different testing context.
