4Grammar and explanations
Because of: –сны улмаас
улмаас means "because of, due to", and like most postpositions it wants a genitive in front of it. To give an event as the cause, put the verb in the past participle –сан and give it the genitive. The vowel of –сан drops: болсон → болсны, байсан → байсны, явсан → явсны.
Ноолуурын үнэ өндөр байсны улмаас малчид олон ямаатай болсон.cashmere-GEN price high be-PART-GEN because herder-PL many goat-COM become-PAST"Because the price of cashmere was high, herders came to keep a lot of goats."
With a plain noun, use its genitive: борооны улмаас (because of the rain), зудын улмаас (because of the dzud).
Зудын улмаас олон мал үхсэн.Many animals died because of the dzud.
The negative past –аагүй takes a short genitive –н: ороогүйн улмаас, "because it did not fall".
Бороо ороогүйн улмаас өвс ургаагүй.rain fall-PAST-NEG-GEN because grass grow-PAST-NEG"Because it didn't rain, the grass didn't grow."
As a result of: –сны үр дүнд
үр дүн is "result". The phrase is built exactly like –сны улмаас, but the outcome it introduces is usually good, or at least neutral:
Малчид хамтран ажилласны үр дүнд өвс дахин ургасан.herder-PL together work-PART-GEN result-DAT grass again grow-PAST"As a result of the herders working together, the grass grew again."
The reason is…: учир нь
учир нь opens a new sentence and gives the reason for the one before. The sentence often ends in юм:
Бэлчээр доройтож байна. Учир нь мал хэт олон болсон юм.The pasture is degrading. The reason is that there are far too many animals.
Which one to choose
| Form | Where it goes | Register | Typical outcome |
|---|
| –сны улмаас | inside the sentence, before the result | formal | usually bad |
| –сны үр дүнд | inside the sentence, before the result | formal | usually good |
| учир нь | at the start of the next sentence | neutral | gives a reason |
| –сан учраас | inside the sentence (lesson 95) | everyday | any |
For the other direction, from cause to result, use тиймээс ("so, therefore") at the start of the next sentence: Ямаа өвсийг үндсээр нь иддэг. Тиймээс өвс ургахгүй.
