Sentence explanations

1. Ich verstehe jetzt.

   I understand now.

   Ich

   I

   verstehe

   understand

   jetzt

   now

   More detail

   Ich means “I” and identifies the speaker. German personal pronouns change with grammatical role; ich is the first-person singular form used here as the subject. Example: Ich lerne. — “I am learning.” verstehe is the first-person singular present-tense form of verstehen (“to understand”): ich verstehe. The ending -e marks this verb form with ich; the infinitive is verstehen. Example: Ich verstehe die Frage. — “I understand the question.” In the supplied neighboring sentence, Ich verstehe nicht uses the same verb form, with nicht adding negation. jetzt means “now” and places the understanding at the current time. It is an adverb and does not change form. Example: Ich arbeite jetzt. — “I am working now.” Together, Ich verstehe gives “I understand,” and jetzt specifies when: “I understand now.”

2. Ich verstehe nicht.

   I do not understand.

   Ich

   I

   verstehe

   understand

   nicht

   not

   More detail

   Ich is the German first-person singular pronoun: it means “I” when the speaker refers to themself. It does not identify any additional participant. Example: Ich lerne. — “I am learning.” verstehe is the present-tense first-person singular form of verstehen (“to understand”): ich verstehe. The ending belongs to the verb, and the subject Ich tells us who understands. Example: Ich verstehe die Frage. — “I understand the question.” nicht is the standard negating word here. It reverses the positive statement Ich verstehe (“I understand”), producing “I do not understand.” In the related sentence Ich weiß nicht, nicht likewise negates weiß, but weiß means “know,” not “understand.” Together, Ich verstehe nicht. means “I do not understand.” The subject comes first, followed by the conjugated verb, and nicht supplies the negation. This is a common, reusable way to state that the speaker does not understand something; the sentence does not specify what the missing understanding concerns.

3. Ich weiß nicht.

   I do not know.

   Ich

   I

   weiß

   know

   nicht

   not

   More detail

   Ich means “I.” It is the first-person singular subject pronoun. The same form is used regardless of the speaker’s gender: Ich lerne. — “I am learning.” weiß is the present-tense first-person singular form of wissen, “to know” or “to have information.” The form is irregular: ich weiß, du weißt, wir wissen. German distinguishes wissen for facts or information from kennen for familiarity with a person, place, or work. Example: Ich kenne Berlin. — “I know Berlin / I am familiar with Berlin.” nicht means “not.” Here it negates the speaker’s knowing, giving the meaning “do not know.” In a simple clause, nicht commonly appears after the finite verb when the whole statement is being negated. Example: Ich weiß das nicht. — “I do not know that.” Together, Ich weiß nicht. is a complete present-tense statement: “I do not know.” The pattern Ich weiß nicht, ... can introduce information the speaker cannot provide, as in Ich weiß nicht, was das ist. — “I do not know what that is.”

4. Was meinst du?

   What do you mean?

   Was

   what

   meinst

   mean

   du

   you

   More detail

   Was means “what” and asks for the content or meaning being referred to. It is an interrogative pronoun here. Compare wer (“who”), which asks about a person. meinst is the present-tense form of meinen (“to mean” or “to intend”) for du (“you”): ich meine, du meinst. In this sentence, it asks about the meaning the other person intends, not simply about an opinion. Example: Was meinst du damit? — “What do you mean by that?” du is the informal singular “you” pronoun. It is the subject of meinst; the verb form meinst agrees with it. In a German question beginning with a question word, the finite verb comes before the subject: Was + meinst + du. Together, Was meinst du? asks the other person to clarify the meaning of what they said: “What do you mean?”

5. Verstehst du mich?

   Do you understand me?

   Verstehst

   understand

   du

   you

   mich

   me

   More detail

   Verstehst is the present-tense second-person singular form of verstehen (“to understand”). The verb keeps its stem vowel in this form: verstehen → du verstehst. The ending -st marks the informal singular du form. Example: Verstehst du die Frage? — “Do you understand the question?” du is the nominative pronoun for one person addressed informally. It identifies the subject, while its form does not indicate the person’s gender. In a German yes/no question, the conjugated verb comes before the subject: Verstehst du ...? mich is the accusative form of ich (“I”), used here for the person directly understood. The useful contrast is ich for the subject and mich for a direct object. Example: Sie sieht mich. — “She sees me.” Together, Verstehst du mich? uses the present-tense verb-first question pattern, with du as the subject and mich as the direct object. It means “Do you understand me?”

6. Kennst du ihn?

   Do you know him?

   Kennst

   know (someone or something)

   du

   you

   ihn

   him

   More detail

   Kennst is the present-tense second-person singular form of kennen, meaning to know or be acquainted with a person, place, or thing. The related verb wissen is used for knowing a fact or piece of information: Ich kenne Berlin means “I know Berlin,” while Ich weiß die Antwort means “I know the answer.” du is the nominative pronoun for one person addressed informally: “you.” With du, many present-tense verbs take the ending -st; here, kennen becomes kennst. The separate formal singular form is Sie, which uses a different verb form: Kennen Sie ihn? means “Do you know him?” ihn is the accusative singular masculine form of er (“he”). It marks the person known in this sentence as the direct object. The corresponding feminine form is sie: Kennst du sie? means “Do you know her?” Together, Kennst du forms a present-tense yes-or-no question addressed informally to one person, and ihn identifies the person known as “him.” The whole utterance therefore means “Do you know him?”
