Question word + –сан + бэ
To ask what happened, put a question word where the answer will go, put the verb in the past, and end with бэ. The particle is бэ and not вэ because every –сан form ends in н (lesson 18: бэ after в, л, м, н).
| Question word | Question | Meaning |
|---|
| хаана (where) | Хаана байсан бэ? | Where were you? |
| юу (what) | Юу хийсэн бэ? | What did you do? |
| хэзээ (when) | Хэзээ ирсэн бэ? | When did you come? |
| хэн (who) | Хэн ирсэн бэ? | Who came? |
| хэдэн цагт (at what time) | Хэдэн цагт ирсэн бэ? | At what time did you come? |
Чи хаана байсан бэ?you where be-PAST Q"Where were you?"
Сургуульд юу хийсэн бэ?school-DAT what do-PAST Q"What did you do at school?"
Багш юу хэлсэн бэ?teacher what say-PAST Q"What did the teacher say?"
Хэзээ ирсэн бэ? — Дөрвөн цагт ирсэн."When did you get home? — At four o'clock."
The answer takes the place of the question word
Nothing moves in a Mongolian question. Чи хаана байсан бэ? is answered Би сургуульд байсан: the answer sits exactly where хаана was. The answer usually repeats the verb, and the subject can be left out: Сургуульд байсан.
Yes/no questions in the past
Without a question word, end with уу or үү, chosen by the vowels of the verb.
Гэрийн даалгавар хийсэн үү?home-GEN task do-PAST Q"Have you done your homework?"
Музейд очсон уу?museum-DAT go-PAST Q"Did you go to the museum?"
The short answer is the verb itself: Хийсэн. "Yes, I have." or Хийгээгүй. "No, I haven't." (lesson 54).
Same question word, different particle
The particle follows the last word of the question, not the question word. Compare the present Чи хаана байна вэ? "Where are you?" (байна ends in a vowel, so вэ) with the past Чи хаана байсан бэ? "Where were you?" (байсан ends in н, so бэ).
