Add か to the end of a statement to turn it into a question. Word order does not change.
ミラーさんは かいしゃいんですか。
Is Mr Miller a company employee?
ワンさんは いしゃですか。…はい、いしゃです。
Is Mr Wang a doctor? … Yes, he is.
サントスさんは がくせいですか。…いいえ、がくせいじゃ ありません。
Is Mr Santos a student? … No, he isn't.
あのかたは どなたですか。
Who is that person? (polite)
Japanese forms questions simply by adding the particle か at the end — there is no need to invert the word order as in English.
The answer starts with はい (yes) or いいえ (no) and then repeats the predicate: はい、医者です / いいえ、医者じゃ ありません. There is no short “yes, he is” — the noun comes back, in the affirmative or the negative form.
- どなた is a polite word for “who”; the plainer word is だれ.
- In everyday speech the repeated noun is usually dropped in favour of はい、そうです / いいえ、ちがいます — lesson 2 covers そうです.
