Asking How and When
Adverbs—whether in German or English—tell you something about the verb: how, where, or when something is done. Use wie to ask “how” and wann to ask “when.”
You have already used several adverbial phrases: Es geht Andreas gut. (Andreas is doing well.)
langsam (slowly)
leise (quietly)
laut (loudly)
schnell (fast)
Let's look at some sample questions and answers using wie and wann.
Wie fährt dein Bruder? (How does your brother drive?)Er fährt sehr schnell. (He drives very fast.)Wann kommt Tina? (When is Tina coming?)Sie kommt heute. (She's coming today.)Wann ist das Konzert? (When is the concert?)Das Konzert ist morgen. (The concert is tomorrow.)
