4Grammar and explanations
Doing it, or having it done
English says "Bold repairs the car" and "Bold has the car repaired": the second needs an extra verb, "have". Mongolian keeps one verb and slips a suffix in between the stem and the ending. This suffix is the causative: the subject does not do the action but makes, has or lets someone else do it.
Болд машинаа засна.Bold car-REFL repair-PRES-FUT"Bold repairs his car."
Болд машинаа засуулна.Bold car-REFL repair-CAUS-PRES-FUT"Bold has his car repaired."
Three shapes
| After the stem | Suffix | Examples |
|---|
| a consonant | –уул– / –үүл– | засах → засуулах, тайрах → тайруулах, үзэх → үзүүлэх (to show) |
| a long vowel or a diphthong | –лга– / –лгэ– | угаах → угаалгах, хүлээх → хүлээлгэх, уух → уулгах (to give a drink) |
| a few old verbs | –га– / –гэ– | гарах → гаргах (to take out), хүрэх → хүргэх (to take someone somewhere) |
Only the first two are living patterns. Learn the verbs in –га– as words of their own, and never build a causative you have not met: a guess may give a word that does not exist.
Who does the work: the instrumental
The person who actually does the job stands in the instrumental, the case of автобусаар (by bus):
Би түүгээр засуулдаг.I he-INS repair-CAUS-HAB"I have it repaired by him."
Номин найзаараа үсээ тайруулсан.Nomin friend-INS-REFL hair-REFL cut-CAUS-PAST"Nomin had her hair cut by her friend."
A causative is a complete verb
Once the suffix is in place, the new verb takes every ending you know, and the ending follows the vowel of the suffix: - засуулна (will have repaired), засуулсан (had repaired), засуулъя (let's have it repaired), засуулаарай (have it repaired, please) - хүлээлгэсэн (kept waiting), as in Хүлээлгэсэнд уучлаарай! "Sorry to have kept you waiting!" - with битгий: Битгий хүлээлгээрэй! "Don't keep me waiting!"
Old friends that are causatives
Some verbs you already know are causatives in disguise: үзүүлэх (to show) is "to make see", явуулах (to send) is "to make go", and сургах (to teach, to train) is "to make learn". English uses three unrelated words; Mongolian shows you the family.
