The Sasun and Mush dialects are also spoken in modern-day Armenian villages such as Bazmaberd and Sasnashen.

Forms of the Karin dialect of Western Armenian are spoken by several hundred thousand people in Northern Armenia, mostly in Gyumri, Artik, Akhuryan, and around 130 villages in the Shirak province,[5] and by Armenians in Samtskhe–Javakheti province of Georgia (Akhalkalaki, Akhaltsikhe).

[6] A mostly diasporic language and one that is not an official language of any state, Western Armenian faces extinction as its native speakers lose fluency in Western Armenian amid pressures to assimilate into their host countries.

According to Ethnologue, there are 1.58 million native speakers of Western Armenian, primarily in Turkey, Armenia, Georgia, Lebanon, and Iraq.

According to Glottolog, Antioch, Artial, Asia Minor, Bolu, Hamshenic, Kilikien, Mush-Tigranakert, Stanoz, Vanic and Yozgat are the main dialects of Western Armenian.

[10] There are notable diaspora L2 Western Armenian speakers in Lebanon (Beirut), Syria (Aleppo, Damascus), California (Fresno, Los Angeles), and France (Marseilles).

Shushan Karapetian, in her evaluation of both the Eastern and Western dialects of Armenian, concludes that heritage languages, in the face of an English dominant society, rapidly die out within no more than 2 generations, calling America a "linguistic graveyard.

Western Armenian has ten environments in which two vowels in the orthography appear next to each other, called diphthongs.

The /w/ glide is not used except for foreign proper nouns, like Washington (by utilizing the "u" vowel, Armenian "ու").

There are several declensions, but one is dominant (the genitive in i) while a half-dozen other forms are in gradual decline and are being replaced by the i-form, which has virtually attained the status of a regular form: գիտութեանց գիտութիւնով Like English and some other languages, Armenian has definite and indefinite articles.

The indefinite article in Western Armenian is /mə/, which follows the noun: ator mə ('a chair', Nom.sg), atori mə ('of a chair', Gen.sg) The definite article is a suffix attached to the noun, and is one of two forms, either -n (when the final sound is a vowel) or -ə (when the final sound is a consonant).

The "present" tense in Western Armenian is based on three conjugations (a, e, i): The present tense (as we know it in English) is made by adding the particle gə before the "present" form, except the defective verbs em (I am), gam (I exist, I'm there), unim (I have), kidem (I know) and gərnam (I can), while the future is made by adding bidi: For the exceptions: bidi əllam, unenam, kidnam, garenam (I shall be, have, know, be able).

In vernacular language, the particle "gor" is added after the verb to indicate present progressive tense.
