4Grammar and explanations
"Than" is an ending
Mongolian has no word for "than" and no "-er" ending on the adjective. To compare, put the thing you compare against into the ablative, the "from" case of lesson 36, and leave the adjective exactly as it is, at the end of the sentence.
Хөдөө хотоос тайван.countryside city-ABL calm"The countryside is calmer than the city."
Парис Улаанбаатараас том.Paris Ulaanbaatar-ABL big"Paris is bigger than Ulaanbaatar."
Word for word: "the countryside, from the city, calm". Measured from the city, the countryside is calm. The order is always the same: the thing described, then the standard with –аас / –оос / –ээс / –өөс, then the adjective. The vowel of the ending follows the standard, never the adjective: хотоос, Батаас, Номиноос, хүнээс, хөдөөнөөс.
Comparing people
The pronouns have their own ablative forms, which you met in lesson 36: надаас (than me), чамаас (than you, familiar), танаас (than you, polite), түүнээс (than him, than her).
Номин надаас залуу.Nomin I-ABL young"Nomin is younger than me."
илүү: stressing "more"
You can put илүү (more) between the standard and the adjective. It is optional, because the ablative already says "than", but it makes the "more" explicit and is very common in speech.
Ганбаатар Батаас илүү хүчтэй.Ganbaatar Bat-ABL more strong"Ganbaatar is stronger than Bat."
More and fewer
With олон (many) and цөөн (few), the same pattern counts things:
Хөдөө мал хүнээс олон.countryside livestock person-ABL many"In the countryside there are more animals than people."
For "less", Mongolian normally uses the opposite adjective instead of a word for "less": цөөн (few), жижиг (small), хүйтэн (cold). "The city is less calm" becomes "the countryside is calmer": Хөдөө хотоос тайван.
Watch the standard
The ending goes on the standard, so it is the standard that may change shape. A short vowel can drop out: өчигдөр → өчигдрөөс, үхэр → үхрээс. A long vowel can add н: хөдөө → хөдөөнөөс.
Өнөөдөр өчигдрөөс хүйтэн.today yesterday-ABL cold"Today is colder than yesterday."
Asking "which one?"
To ask about two things, put two yes/no questions side by side: Хот сайхан уу, хөдөө сайхан уу? "Is the city nicer, or the countryside?"
