Basic Sentence Structure (Word Order)
How does word order change in a W-question (interrogative)?
The W-word (wer, was, wann, wo, warum, wie, etc.) is in the first position, and the conjugated verb is in the second position.
Example
Wann (1) kommst (2) du (3)? (When are you coming?)
Wo (1) wohnst (2) du (3)? (Where do you live?)
