Understanding noun cases is one of the most important steps in your Armenian language journey.

Cases simply tell you the exact role a word plays in a sentence based on its ending.

English uses word order and prepositions to show meaning, while Armenian changes the end of the noun itself.

This guide breaks down exactly how Armenian noun cases and declensions work without any confusing academic jargon.

What are Armenian noun cases?

A noun case is a grammatical category that changes the spelling of a noun to show its function.

You can think of cases like English prepositions (in, on, to, from, with) permanently attached to the end of a word.

Instead of adding a separate word before the noun to say “with a pen”, Armenian simply takes the base word for “pen” and attaches a specific “with” suffix to it.

This system makes sentence structure highly flexible.

Because the word endings tell you exactly who is doing what, you can often mix up the word order in Armenian without changing the meaning of the sentence.

The 7 Armenian noun cases (Eastern vs. Western)

The Armenian language is split into two major branches: Eastern Armenian and Western Armenian.

Eastern Armenian (spoken in the Republic of Armenia) has 7 distinct noun cases.

Western Armenian (spoken largely by the diaspora) officially has 6 noun cases.

Western Armenian lacks the Locative case entirely and uses a separate word to show location instead.

Western Armenian also heavily blends the Accusative case into the Nominative and Dative cases.

For this guide, we’ll focus primarily on the 7 Eastern Armenian cases, while pointing out Western differences where they matter most.

Nominative case (ուղղական)

The Nominative case is the easiest case to learn because it’s just the dictionary form of the word.

It’s used for the subject of the sentence.

The subject is the person, place, or thing performing the action.

In this sentence, the student (ուսանող) is in the Nominative case because they’re the one doing the reading.

Accusative case (հայցական)

The Accusative case marks the direct object of a sentence.

The direct object is the noun that’s receiving the action of the verb.

In Armenian, the Accusative case behaves differently depending on whether the noun is an inanimate object or an animate living being.

For inanimate objects (like books, cars, or cities), the Accusative looks exactly like the Nominative case.

For animate beings (like people or animals), the Accusative takes the exact same ending as the Dative case (which usually ends in -ին).

Genitive case (սեռական)

The Genitive case is used to show possession.

It’s the Armenian equivalent of adding an apostrophe and an “s” (‘s) or using the word “of” in English.

For most regular nouns, you form the Genitive case by adding the letter -ի (-i) to the end of the word.

Dative case (տրական)

The Dative case marks the indirect object of a sentence.

It translates to doing something “to” or “for” someone.

In modern Armenian, the Dative case looks entirely identical to the Genitive case in its spelling.

The only difference is that Dative nouns often take the definite article -ն (-n) or -ը (-y) at the end, depending on the following word.

Ablative case (բացառական)

The Ablative case shows movement away from something, or the origin of something.

It translates directly to the English word “from”.

In Eastern Armenian, this is usually formed by adding the suffix -ից (-its) to the base word.

In Western Armenian, the Ablative case ending is different and usually ends in -է (-e) or -էն (-en).

Instrumental case (գործիական)

The Instrumental case describes the means by which an action is performed.

It usually translates to “with” or “by means of” in English.

You form this case by adding the suffix -ով (-ov) to the noun in both Eastern and Western Armenian.

Locative case (ներգոյական)

The Locative case tells you where an action takes place.

It translates to English prepositions like “in”, “on”, or “at”.

In Eastern Armenian, you form the Locative case by adding -ում (-um) to the end of the word.

Western Armenian doesn’t use this case suffix at all.

Instead, Western speakers use the Genitive case of the noun followed by the separate word մէջ (mech), which means “inside”.

Armenian declensions (how words change)

A “declension” is simply the pattern that a noun follows when it changes cases.

You can think of declensions as noun families.

Different families take slightly different vowels when they change into the Genitive or Dative cases.

The most common declension in Armenian is the “i-declension” (ի-հոլովում).

This means the vast majority of nouns will use the letter -ի (-i) as their base connecting vowel for their case endings.

Here’s an HTML table showing how a regular inanimate noun like քաղաք (city) declines in Eastern Armenian.

There are other declensions (like words that use -ա or -ոջ instead of -ի), but the regular i-declension covers the vast majority of vocabulary you’ll learn as a beginner.

Focus entirely on recognizing the primary case endings (-ից, -ով, -ում) first.
