What istagan predlog bilan ishlatilishi mumkin. Predlog whatdan oldin, fe’ldan keyin, agar to‘ldiruvchi bo‘lsa, to‘ldiruvchidan keyin qo‘yilishi mumkin:
By what is this engine driven? Bu motor nima bilan yuradi?With what did you cut it? Siz uni nima bilan kesdingiz? About what was he speaking to you? U Sizga nima haqda gapi-rayotgan edi? At what are you working? Siz nima ustida ishlayapsiz? What was he speak-ing to you about? What are you working at?
What qanday ma’nosida olmosh-sifat bo‘lib keladi, otning ko’rsatkichi bo‘lganligi uchun, whatdan keyin kelgan ot oldida artikl ishlatilmaydi, chunki bitta ot oldida faqat bitta ko‘rsatkich ishlatilishi mumkin:	What question did he ask? U qanday savol so’radi? What books did you buy? Siz qanday kitoblar sotib oldingiz?

Izoh: Savol kishining ismi yoki sharifini bilish maqsadida berilgan bo‘lsa who ishlatiladi: Who is he? –He is Olimov?
