Learn German: Kennst du die Stadt? - Do you know the city?

German has two common verbs for 'to know'. Use wissen for knowing facts or information. Use kennen when you are familiar with a person, place, or thing. Since you are asking if someone is familiar with a city (die Stadt), kennen is the right choice.

Does kennen have a vowel change in the present tense like the verbs in this lesson?

No! Unlike strong verbs with an 'a to ä' change (like fahren becoming fährst), kennen is completely regular in the present tense. You simply take the stem kenn- and add the standard -st ending for du, giving you kennst.

Where is the word for 'do' in this question?

German doesn't use helper words like 'do' or 'does' to make questions. Instead, you just move the conjugated verb to the front. The statement 'You know' is du kennst, so to ask 'Do you know?', you just swap the order to kennst du.

Why is it die Stadt? Doesn't the word look masculine or neuter?
