Grammar

A yes/no question normally puts the finite verb first: Hast du Zeit? Wohnen Sie hier? In an information question, put the question expression first, then the finite verb: Wo wohnst du? Wie viel kostet das? The multiword wie viel occupies one position.

Also recognise Was für ein …? asking what kind of thing, versus Welcher …? choosing which one in a relevant set: Was für ein Auto suchst du? Welches Auto ist deins? Learn their endings as the noun/case patterns become familiar.

Core question words:
wer who;
was what;
wo where/location;
wohin where to;
woher where from;
wann when;
wie how;
warum why;
wie lange how long;
wie oft how often;
wie viel how much;
wie viele how many;
welcher/welche/welches which, with endings reflecting the noun/case.

Example

Wo wohnen Sie? Wohin fahren Sie morgen?

English

Where do you live? Where are you travelling to tomorrow?

Hinglish

Aap kahaan rehte hain? Kal aap kahaan jaa rahe hain?
