In professional English, indirect questions are often more appropriate than direct questions. A direct question like 'What is the deadline?' is not rude, but 'Could you tell me what the deadline is?' sounds more polite and professional. Notice the grammar: in indirect questions, there is no subject-verb inversion. Direct: 'When does the meeting start?' Indirect: 'Could you tell me when the meeting starts?' For yes-no questions, use whether or if: 'Is the project on track?' becomes 'Could you confirm whether the project is on track?' Common openers include: Do you know / I was wondering / I would like to know / Could you clarify.

💡 Did you know? Japanese has an entire grammatical register — keigo — specifically for polite and formal speech. English is less extreme but indirect questions perform a similar social function, helping speakers show respect and avoid imposing.
