Learning Objective
Advanced Wh-Questions: Form, Choice and Register
Choose a wh-form by grammatical role and register, and maintain correct word order in direct and embedded questions.
Clear Explanation
Wh-forms replace a missing constituent. Subject questions keep statement order; other direct questions normally require subject-auxiliary inversion. Formal register may place a preposition before whom or which.
Form and Structure
wh-subject + verb; wh-non-subject + auxiliary + subject + verb; wh + statement order in embedded question
“Who approved the revision?”
Whom survives most strongly after a fronted preposition and in formal writing. In many other object positions, who is standard in contemporary speech and much writing.
Meaning and Use
Grammatical role
Who/what as subject does not trigger do-support; an object question normally does.
“Who called you? Who did you call?”
Choice from a set
Which is used when the relevant alternatives are contextually limited; what is more open-ended.
“Which of these routes is safer?”
Register and prepositions
Fronted prepositions with whom/which are formal; stranded prepositions are normal in neutral conversation.
“Who were you speaking to?”
Common Errors and Meaning Traps
Who did approve the revision?
Who approved the revision?
A neutral subject question does not require do-support.
Could you tell me where is the office?
Could you tell me where the office is?
An embedded question uses statement word order.
To who should I send it?
To whom should I send it?
After a fronted preposition in formal style, use the object form whom.
Guided Practice
