Question Words
A1
Question words (who, what, where, when, why, how, which, whose) start information questions. They come before the auxiliary verb and subject.
Question Tags
B1
Question tags are short questions added to the end of statements to check information or invite agreement. A positive statement takes a negative tag, and a negative statement takes a positive tag.
Subject vs Object Questions
B1
When the question word is the subject (who or what does the action), no auxiliary is needed and word order stays like a statement. When it is the object, the usual question form with an auxiliary applies.
