Mongolian Grammar: Understanding the basics

Mongolian Grammar


In this lesson…

we would like to give you a basic overview of some key Mongolian grammar concepts.

Here you can find the basic sentence structure and the most common tenses that appear in the Mongolian language, as well as many common Mongolian grammar forms which appear frequently.


1. Mongolian Sentence Structure


Mongolian sentence structure is different from English & some other languages in that Mongolian language structure follows the form: Subject – Time – Object- Predicate (verb). Which can be memorized as STOP.

So, in an English sentence, we have SVO (subject, verb, object). For example, I drink coffee. ‘I’ is the subject, drink is the verb and coffee is the object. However, in Mongolian this is reversed:  the verb and object are switched, so in Mongolian, the order is SOV (Subject – Object – Verb).

For example: 

Би кофе уудаг. [I coffee drink.]

In that example, we have S O V. Let’s see more examples:

Би монгол хэл сурдаг (I Mongolian study) – I study Mongolian.

Би хоол хийдэг (I food make) –  I make food. 

Би ном уншдаг (I book read) – I read a book. 

One thing that makes it challenging for english speakers is that you have to wait until the very end of the sentence to understand the meaning since the verb, which is often the most important word, is always at the end. 

That’s right!  No matter how long a sentence is in Mongolian, the verb will always be at the end.  Sometimes you may be waiting and waiting to see what the subject in the sentence is doing, so it could be quite frustrating.  For example:

Би англи хэл, испани хэл, франц хэл, япон хэл мэдэхгүй.

In this example, someone was listing many languages and you might assume they would end by saying that they know all of these.  But as it turns out, the last word was medexgui (don’t know), so actually the speaker knows none of these languages, but we didn’t know until the very last word!

So that is the basic sentence structure: SOV. But now let’s add the time, for example:

I drink coffee in the morning.  In this English sentence, the time is at the end (the morning)

But in Mongolian, it would be: Би өглөө кофе уудаг (I  morning coffee drink) – I drink coffee in the morning. 


And a couple other examples: 

Би орой хоол хийдэг (I evening food make) – I cook in the evening. 

Би өдөр бүр ном уншдаг (I everyday book read) – I read books every day.

Again, as you can see, the time is often after the subject and we have an acronym which will easily help you remember this order.  It is: STOP, Which is: S(subject)+T(time)+O(object)+P(predicate which is verb). So remember to STOP!!

Let’s look at more examples:

Би өчигдөр монгол хэл сурсан (I yesterday study Mongolian.) – I studied Mongolian yesterday. 

Би маргааш хоол хийнэ (I tomorrow make food ) – I will cook tomorrow. 

Би өдөр бүр монгол хэл сурдаг (I everyday Mongolian study) – I study Mongolian every day.

Although the Subject-Object-Verb order is always the same, the TIME may sometimes change, depending on what you emphasize.  Sometimes you can say the time first. For example; 

Өчигдөр би монгол хэл сурсан (Yesterday I Mongolian Studied.) – I studied Mongolian yesterday. 

Маргааш би ном уншина (Tomorrow I book will read ) – I will read a book tomorrow. 

Hopefully, you are still following me, so now we have STOP, but let’s add one last thing to get a bit more advanced:

Let’s add location/place here: 

Би өчигдөр ресторанд оройн хоол идсэн (I yesterday at restaurant dinner ate) – I ate dinner at a restaurant yesterday. 

Би маргааш гэрт оройн хоол иднэ (I tomorrow at home dinner will eat) – I will eat dinner at home tomorrow. 

As you can see the location is added before the object.

This is the usual order, but if you really want to emphasize the object, you can sometimes say it before the location. For example: 

Би өчигдөр оройн хоол ресторанд идсэн. [I ate dinner at a restaurant yesterday.]

Би маргааш оройн хоол гэрт иднэ. [I will eat dinner at home tomorrow.] 

So in both of these examples, the location is added after the time and the only difference is whether it is before or after the object.



2. Present Simple Tense (V + даг/даггүй4 )

The present tense is used to talk about habitual, repeated, or long-term activities.

For example, Би дандаа алхдаг – I always walk.

даг (-дэг, –дог, –дөг) is added to a verb stem according to vowel harmony. (click the link to review vowel harmony on our youtube channel)

даггүй (-дэггүй, –доггүй, –дөггүй) is used for negative.

More examples:

Бид нар ер нь Зайсан явдаг – We usually go to Zaisan.

Бид нар хэзээ ч зах явдаггүй – We never go to the market.


3. Past Simple Tense ( V +  сан4 аа4 гүй)

The past tense suffix –сан (-сэн, –сон, –сөн) is used to describe an action that happened at a specific time in the past.

For example:

Би өчигдөр ажилласан – I worked yesterday.

The negative form is expressed with the suffix –аагүй (-ээгүй, –оогүй, –өөгүй) according to vowel harmony.

Би өчигдөр ажиллаагүй – I didn`t work yesterday.

More examples:

Би өчигдөр сургууль явсан – Yesterday I went to school.

Би өчигдөр дэлгүүр яваагүй – Yesterday I didn’t go to the store.


4. Expressing action in the future (V +  на/хгүй)

-на (-нэ, -но, -нө) is the suffix that expresses an action that will take place sometime in the future. 

For example:

Би маргааш ажиллана.                     I will work tomorrow.

Note:   In spoken language the vowels with -на (-нэ, -но, -нө) will be dropped according to the rule where single vowels are always dropped.

хгүй is used for negative form which added to the verb stem.

Би маргааш ажиллахгүй.

х will be added to make Interrogative form.

Та маргааш ажиллах уу? – Will you work tomorrow?

Other examples:

Тэр маргааш зах явна – Tomorrow he/she will go to the market.

Тэр маргааш кафе явахгүй – Tomorrow he/she will not go to the cafe.
