How to Say 'I Don't Understand' in German: 15 Natural Phrases

To say “I don’t understand” in German, use Ich verstehe nicht /ɪç fɛɐ̯ˈʃteːə nɪçt/. If you mean “I don’t understand that,” say Ich verstehe das nicht /ɪç fɛɐ̯ˈʃteːə das nɪçt/. In real conversations, the most effective option is often a polite clarification such as Können Sie das bitte wiederholen? /ˈkœnən ziː das ˈbɪtə ˌviːdɐˈhoːlən/, meaning “Could you repeat that, please?”

German has more than 130 million speakers worldwide when first- and second-language speakers are counted, according to Ethnologue. It is an official language in six European countries, including Germany, Austria, Switzerland, Liechtenstein, Belgium, and Luxembourg, so the exact accent and vocabulary you hear can vary.

The good news is that asking for clarification is normal and expected. A clear sentence, a polite tone, and the right form of “you” will help you much more than pretending you understood. Start with these phrases, then see how to make them sound natural in shops, classrooms, offices, and everyday conversations.

For basic German conversations, pair these phrases with greetings and farewells from our guides to saying hello in German and saying goodbye in German. Being able to open, repair, and close a conversation makes a beginner sound more prepared than knowing isolated vocabulary.

The core sentence: say it clearly

Ich verstehe nicht

Ich verstehe nicht /ɪç fɛɐ̯ˈʃteːə nɪçt/ means “I don’t understand.” It is a complete sentence and works when the context is obvious.

Use it after someone gives you directions, explains a rule, or says something you could not follow. In casual situations, it is direct and completely acceptable.

German often puts nicht /nɪçt/, meaning “not,” later in the sentence than an English speaker expects. The verb verstehen /fɛɐ̯ˈʃteːən/ comes second after ich /ɪç/, and the negative word completes the thought.

Do not worry about producing the German ch sound perfectly at first. The sound in ich /ɪç/ is made with the tongue high and air passing gently through the middle of the tongue. It is not exactly English “sh” or “k.” Clear communication matters first, and you can improve this sound through focused listening.

Add the thing you do not understand

Ich verstehe das nicht

Ich verstehe das nicht /ɪç fɛɐ̯ˈʃteːə das nɪçt/ means “I don’t understand that.” Adding das /das/ makes the sentence feel more complete when referring to a statement, document, instruction, or explanation.

A particularly useful variation is Ich verstehe das nicht ganz /ɪç fɛɐ̯ˈʃteːə das nɪçt ɡants/, literally “I don’t understand that completely.” This is a good choice when you understood part of what was said but need help with one detail.

Ich habe das nicht verstanden

Ich habe das nicht verstanden /ɪç ˈhaːbə das nɪçt fɛɐ̯ˈʃtandən/ means “I didn’t understand that.” Use it just after someone has spoken, especially if you missed their last sentence.

This form uses the German perfect tense, which is common in spoken German when describing a completed event. Helbig and Buscha’s Deutsche Grammatik: Ein Handbuch für den Ausländerunterricht treats this verb-final participle pattern as a central feature of German clause structure.

Ask for the repair you need

Saying “I don’t understand” is useful, but a follow-up request gets the conversation moving again. Tell the speaker whether you need repetition, slower speech, an explanation, or a definition.

Können Sie das bitte wiederholen?

Können Sie das bitte wiederholen? /ˈkœnən ziː das ˈbɪtə ˌviːdɐˈhoːlən/ means “Could you repeat that, please?” This is the best all-purpose phrase for strangers, staff, teachers, doctors, and professional contacts.

The verb wiederholen /ˌviːdɐˈhoːlən/ means “to repeat.” Notice that it moves to the end in this question because können /ˈkœnən/ is a modal verb. This is also why German questions can sound different from their English equivalents.

Kannst du das bitte wiederholen?

Kannst du das bitte wiederholen? /kanst duː das ˈbɪtə ˌviːdɐˈhoːlən/ has the same meaning, but it uses informal du /duː/. Say it to friends, close classmates, children, relatives, or people who have invited you to use du.

The distinction between Sie /ziː/ and du /duː/ is not merely grammar. It signals social distance, respect, and familiarity. The Institut für Deutsche Sprache explains that forms of address are part of how German speakers organize interpersonal relationships.

Können Sie bitte langsamer sprechen?

Können Sie bitte langsamer sprechen? /ˈkœnən ziː ˈbɪtə ˈlaŋzaːmɐ ˈʃpʁɛçən/ means “Could you speak more slowly, please?” It is more useful than asking for repetition when you are catching only fragments because the speaker is moving too fast.

For friends, change only Sie /ziː/ to du /duː/: Kannst du bitte langsamer sprechen? /kanst duː ˈbɪtə ˈlaŋzaːmɐ ˈʃpʁɛçən/.

Ask about one word or phrase

Was bedeutet das?

Was bedeutet das? /vas bəˈdɔɪ̯tət das/ means “What does that mean?” Use it when you heard a specific unfamiliar word but otherwise understand the conversation.

You can replace das /das/ with the word you need explained. For example, Was bedeutet Rechnung? /vas bəˈdɔɪ̯tət ˈʁɛçnʊŋ/ asks what Rechnung /ˈʁɛçnʊŋ/, “bill” or “invoice,” means.

Wie sagt man das auf Deutsch?

Wie sagt man das auf Deutsch? /viː zakt man das aʊf dɔɪ̯tʃ/ means “How do you say that in German?” It is helpful when you know the idea in your own language but cannot find the German word.

This phrase can turn an awkward moment into a mini lesson. In a café, shop, or language exchange, many people will appreciate that you are making an effort rather than immediately switching to English.

Können Sie das erklären?

Können Sie das erklären? /ˈkœnən ziː das ɛɐ̯ˈklɛːʁən/ means “Could you explain that?” Use it for a rule, process, instruction, or complicated point.

It is slightly broader than asking for repetition. Repeating a confusing sentence at the same speed may not solve the problem, while an explanation can provide the missing context.

Natural replies when someone helps you

After the other person repeats or explains something, show that you are following. A simple Danke /ˈdaŋkə/ is enough, but these phrases are especially useful.

Writing an unfamiliar word down is particularly practical in German because long compounds can be easier to decode on paper than in fast speech. If someone says Krankenversicherungskarte /ˈkʁaŋkn̩fɛɐ̯ˌzɪçəʁʊŋskaʁtə/, seeing its parts can make it less intimidating.

Common mistakes to avoid

Do not say “Ich nicht verstehe”

English speakers sometimes translate word by word and produce Ich nicht verstehe. German word order requires Ich verstehe nicht /ɪç fɛɐ̯ˈʃteːə nɪçt/ in a normal main clause.

The verb usually takes second position in a standard German statement. This verb-second pattern is one of the clearest structural habits to build early.

Do not use informal du automatically

Using du /duː/ with every adult is not always offensive, but it can feel overly familiar in formal settings. Learn the formal version first, then move to informal speech when the relationship clearly permits it.

Do not over-apologize

You do not need to say Entschuldigung /ɛntˈʃʊldɪɡʊŋ/ before every sentence. Use it to get attention or soften an interruption, then make a specific request.

A concise Entschuldigung, können Sie das bitte wiederholen? /ɛntˈʃʊldɪɡʊŋ ˈkœnən ziː das ˈbɪtə ˌviːdɐˈhoːlən/ is natural. Repeated apologies can make you sound less confident without making communication easier.

Short phrases for real-life situations

In a noisy bar or crowded station, Wie bitte? /viː ˈbɪtə/ is a quick, polite “Pardon?” It is lighter than saying you do not understand the entire topic.

If you did not hear rather than did not understand, say Ich habe Sie nicht verstanden /ɪç ˈhaːbə ziː nɪçt fɛɐ̯ˈʃtandən/ in formal speech. With a friend, use Ich habe dich nicht verstanden /ɪç ˈhaːbə dɪç nɪçt fɛɐ̯ˈʃtandən/.

For a phone call, try Die Verbindung ist schlecht /diː fɛɐ̯ˈbɪndʊŋ ɪst ʃlɛçt/, meaning “The connection is bad.” This removes blame from either speaker and explains why you need them to repeat themselves.

If someone is using difficult language, say Können Sie das einfacher sagen? /ˈkœnən ziː das ˈaɪ̯nfaxɐ zaːɡən/, meaning “Could you say that more simply?” This is useful with bureaucracy, medical instructions, academic explanations, and technical vocabulary.

Make “I don’t understand” part of your German toolkit

The best phrase to memorize is Ich verstehe das nicht ganz /ɪç fɛɐ̯ˈʃteːə das nɪçt ɡants/. It is honest, polite, and less abrupt than a bare “I don’t understand.”

Then add one request: Können Sie das bitte wiederholen? /ˈkœnən ziː das ˈbɪtə ˌviːdɐˈhoːlən/. Together, those two sentences let you handle a surprising number of real conversations.
