4Grammar and explanations
No verb "to have"
English says "I have a sister". Mongolian has no verb for "have". Instead it takes the ending you met in настай (lesson 23) and puts it on the thing you have: –тай, –той or –тэй, which means "with". Би эгчтэй says, word for word, "I (am) with an older sister". There is no verb in the sentence at all.
Би эгчтэй.I sister-COM"I have an older sister."
Тэр нэг дүүтэй.he one sibling-COM"He has one younger brother or sister."
Би олон тоглоомтой.I many toy-COM"I have a lot of toys."
Three forms, chosen by the vowels
This ending has three forms, not four. The vowels of the word decide, as always in Mongolian.
| Ending | after a word with | Examples |
|---|
| –тай | а, у | ахтай, настай |
| –той | о | тоглоомтой, номтой |
| –тэй | э, ө, ү (or only и) | эгчтэй, дүүтэй, өрөөтэй |
There is no form with ө: өрөө (room) gives өрөөтэй. And because the ending starts with a consonant, it simply joins the word as it is: nothing is added and nothing drops.
Asking and answering
For a yes/no question, the particle after –тай and –той is юу; after –тэй it is юү. To ask "how many", put хэдэн before the noun and end with вэ.
Чи ахтай юу?Do you have an older brother?
Та хэдэн хүүхэдтэй вэ?How many children do you have?
Not having: –гүй
To say you do not have something, replace the ending with –гүй, "without". This ending never changes: it is –гүй after every word.
Би ахгүй.I brother-without"I have no older brother."
A second way: Надад … байна
You can also say "to me there is": надад ("to me"), then the thing, then байна. "To you" is танд (polite) or чамд (familiar). You will learn this ending properly in lesson 35.
Надад нэг зураг байна.me-DAT one photo be-PRES-FUT"I have a photo."
Танд зураг байна уу?Do you have a photo?
Use –тай for family, age and the things that describe you; use Надад … байна for something you have with you right now.
