4Grammar and explanations
The reason comes first
English can say "I'm tired because I didn't sleep". Mongolian always gives the reason first, closes it with the word for "because", and puts the result at the end.
Би унтаагүй учраас ядарч байна.I sleep-PAST-NEG because tire-CONV be-PRES-FUT"I'm tired because I didn't sleep."
Word for word: "I, not having slept, because, am tired." The order never changes: reason, then учраас, then the result with the main verb.
учраас after a verb form
учраас follows a verb in one of its participle forms. The form tells you when the reason happened:
- –сан учраас: because something happened. Олон айлд очсон учраас ядарсан. "I'm tired because I visited a lot of families."
- –аагүй учраас: because something did not happen. Унтаагүй учраас…
- –х учраас: because something is going to happen.
Маргааш эрт явах учраас би эрт унтна.tomorrow early go-PART because I early sleep-PRES-FUT"Because I'm leaving early tomorrow, I'll go to bed early."
болохоор: the same job
болохоор does the same work as учраас after a verb form: Зочид шөнө дунд хүртэл байсан болохоор унтаагүй. "Because the guests stayed until midnight, I didn't sleep." It can also follow a noun or an adjective directly:
Хүйтэн болохоор бид гэртээ байна.cold because we home-DAT-REFL be-PRES-FUT"Because it's cold, we're staying at home."
| Pattern | Example | Meaning |
|---|
| –сан учраас | Унтаагүй учраас ядарсан. | I'm tired because I didn't sleep. |
| –сан болохоор | Олон бууз идсэн болохоор унтмаар байна. | I ate lots of buuz, so I want to sleep. |
| noun + болохоор | Баяр болохоор дэлгүүр хаалттай. | It's a holiday, so the shop is closed. |
| –х учраас | Эрт явах учраас эрт унтна. | I'm leaving early, so I'll go to bed early. |
Asking and answering "why?"
Ask with яагаад and end with вэ or бэ, by the rule of lesson 18:
Яагаад унтаагүй вэ?why sleep-PAST-NEG Q"Why didn't you sleep?"
In a quick answer you can stop after the reason: — Яагаад ядарсан бэ? — Унтаагүй болохоор. "Why are you tired?" "Because I didn't sleep."
яагаад гэвэл: "because", at the front
You will also hear the reason given as a second sentence, opened by яагаад гэвэл, literally "if you ask why": Би эрт унтна. Яагаад гэвэл маргааш эрт явна. "I'll go to bed early. Because tomorrow I'm leaving early."
