4Grammar and explanations
Two postpositions: өмнө and дараа
өмнө (before) and дараа (after) are postpositions: separate words that stand after a noun, where English puts "before" and "after" in front. The noun in front of them takes the genitive, the "of" ending of lesson 37.
хоолны өмнөmeal-GEN before"before the meal"
хичээлийн дарааlesson-GEN after"after the lesson"
Word for word, хоолны өмнө is "the meal's before". Never put the postposition first, and never leave the noun bare: хоол өмнө is wrong.
The meals of the day
Each meal name already contains a genitive: өглөөний цай is "the morning's tea", үдийн хоол "noon's food", оройн хоол "the evening's food". To add өмнө or дараа, the last word takes a second genitive. цай and хоол both take –ны:
| Meal | Before | After |
|---|
| өглөөний цай (breakfast) | өглөөний цайны өмнө | өглөөний цайны дараа |
| үдийн хоол (lunch) | үдийн хоолны өмнө | үдийн хоолны дараа |
| оройн хоол (dinner) | оройн хоолны өмнө | оройн хоолны дараа |
Өглөөний цайны өмнө би үнээ саадаг.morning-GEN tea-GEN before I cow milk-HAB"Before breakfast I milk the cows."
With a length of time: "ago" and "later"
Put a number and a time word in front, and өмнө means "ago", дараа means "later" or "in". The number keeps its form before a noun (гурван, хоёр, lesson 23) and takes no ending; only the time word takes the genitive: цаг → цагийн, хоног → хоногийн, жил → жилийн.
гурван хоногийн өмнөthree day-GEN before"three days ago"
хоёр цагийн дарааtwo hour-GEN after"two hours later, in two hours"
A first look: after doing something
To say "after doing", take the past form in –сан / –сон / –сэн / –сөн, give it the genitive, and drop the vowel in front of н: уусан → уусны дараа, идсэн → идсний дараа. You will practise this properly in lesson 144; for now, recognise it.
Цай уусны дараа бид гарлаа.tea drink-PAST-GEN after we go.out-PAST"After drinking tea, we went out."
Where the phrase goes
A time phrase with өмнө or дараа usually opens the sentence or comes right after the subject, and the verb still closes the sentence: Бид хичээлийн дараа явна. "We will leave after the lesson."
