English is one of the languages that emphasizes inquisition by placing interrogative words at the beginning of a sentence.

Who, whom (human)
What, which (nonhuman)
When (time)
Where (location)
Whow (manner)
Why, wherefore (reason)
Whence (source)
Whither (goal)
Whether (choice between alternatives)
