What is the Comitative Case?
The comitative case is a grammatical case used to indicate that someone or something is accompanied by another person or thing. In English, this is often expressed by using the word “with.” In Mongolian, the comitative case is essential for expressing companionship, joint actions, and association in both spoken and written language.
Formation of the Comitative Case in Mongolian
In Mongolian, the comitative case is typically formed by adding specific suffixes to the noun, depending on the vowel harmony and the final sound of the word. The most common comitative suffixes in modern Mongolian are -тай (-tai), -тэй (-tei), and -той (-toi). The choice of suffix depends on the vowels in the root word:
- -тай is used with nouns containing back vowels (a, o, u).
- -тэй is used with nouns containing front vowels (e, ö, ü).
- -той is used with nouns ending in consonants and some specific vowel harmony cases.
Examples of the Comitative Case in Mongolian
- Найзтайгаа сургуульд явсан. (I went to school with my friend.)
- Тэр ээжтэйгээ кино үзсэн. (He watched a movie with his mother.)
- Би номтой сууна. (I am sitting with a book.)
Common Uses of the Comitative Case
1. Expressing Companionship
The primary function of the comitative case is to indicate that someone is accompanied by another person or object. For instance, if you want to say “with a friend” or “with a teacher,” you would use the appropriate comitative suffix in Mongolian.
2. Indicating Joint Actions
The comitative case is used to show that an action is performed together with someone else. This is especially important in daily conversations to clarify who is involved in an activity.
3. Showing Possession or Association
In some contexts, the comitative case can convey a sense of possession or association, similar to saying “with” in English, as in “a house with a garden.”
Tips for Learning and Using the Comitative Case

Common Mistakes and How to Avoid Them

Double-check your suffixes for vowel harmony and noun endings to avoid grammatical errors.
