Armenian grammar exhibits a case system with seven cases. However, it does not classify nouns into grammatical genders. Verbs are also conjugated for tense and mood. Such a system allows Armenian to convey very specific nuances and meanings just by using nouns and verbs alone.
The evolution of the language can be classified into roughly three eras: Classical Armenian, Middle Armenian, and Modern Armenian.
Classical Armenian is dated from the 5th century to the 19th century, even though as a spoken language, only true up until the 11th century. From the 11th century to the 19th century, however, it remained the standard literary language, while Middle Armenian dialects were used vernacularly between the 12th and 18th century. At this time, notable linguistic landmarks include the publication of the first Armenian periodical in 1794. Classical Armenian borrowed many words at this time from Iranian languages, Greek, Arabic, and Persian, which would have an effect on its later linguistic development. Classical Armenian to this day continues to be a liturgical language, most notably for the Armenian Apostolic Church and the Armenian Catholic Church.
The period between the 12th and 18th centuries is where Middle Armenian is placed and refers more to the spoken dialects at this time. As can be seen from the dates, Middle Armenian existed at the same time as Classical Armenian, when the Classical variety was used more for formal purposes. It can also be considered a transition from Classical Armenian to Modern Armenian.
In the 19th century, political and cultural events influenced the development of Armenian as both a literary and vernacular language. First, Armenia was divided with the Eastern part conquered by the Russian Empire and the Western part being under Ottoman control. Furthermore, both of these empires were rivals, and thus, the environments in which Armenian speech communities lived at this time were quite separate between the west and east. Due to this, two major Armenian standard languages were formed, a western standard and an eastern standard.
During this period, despite foreign influences, both standards flourished. Newspapers were published in both standards and education was also conducted with both varieties being employed. As a result, the rate of literacy increased substantially at this time. Moreover, Armenian’s literary tradition continued and adapted to the modern language.
After World War I, Armenia was under control of the Soviet Republic. At this time, Eastern Armenian was used as the official language. Despite the Armenian Genocide in the Ottoman Empire, the diaspora who escaped to various parts of the world has preserved Western Armenian. Eastern Armenian is thus more associated with writers and linguists of the Russian Empire while Western Armenian is closely associated with writers at the time of the Ottoman Empire.
Currently, Armenian is a language with two standardized norms, it’s a pluricentric language without one unifying standard. However, the dialects that are spoken nowadays are mostly mutually intelligible. The language that is spoken in current Armenia is Eastern Armenia while the language of the diaspora is Western Armenia. Both standards remain important as Armenian, as a whole, is a language that unites a certain speech community and culture with a shared history.
