the development of a network of schools where modern Armenian was taught, dramatically increased the rate of literacy (in spite of the obstacles by the colonial administrators), even in remote rural areas. The emergence of literary works entirely written in the modern versions increasingly legitimized the language's existence. By the turn of the 20th century both varieties of the one modern Armenian language prevailed over Grabar and opened the path to a new and simplified grammatical structure of the language in the two different cultural spheres. Apart from several morphological, phonetic, and grammatical differences, the largely common vocabulary and generally analogous rules of grammatical fundamentals allows users of one variant to understand the other as long as they are fluent in one of the literary standards. After World War I, the existence of the two modern versions of the same language was sanctioned even more clearly. The Armenian Soviet Socialist Republic (1920–1990) used Eastern Armenian as its official language, whereas the diaspora created after the Armenian genocide preserved the Western Armenian dialect. The two modern literary dialects, Western (originally associated with writers in the Ottoman Empire) and Eastern (originally associated with writers in the Russian Empire), removed almost all of their Turkish lexical influences in the 20th century, primarily following the Armenian genocide. Geographic distribution The number of Armenian-speakers by country according to official government sources, including censuses and estimates: Phonology Proto-Indo-European voiceless stop consonants are aspirated in the Proto-Armenian language, one of the circumstances that is often linked to the glottalic theory, a version of which postulated that some voiceless occlusives of Proto-Indo-European were aspirated. Stress In Armenian, the stress falls on the last syllable unless the last syllable contains the definite article or , and the possessive articles and , in which case it falls on the penultimate one. For instance, , , but and . Exceptions to this rule are some words with the final letter ( in the reformed orthography) () and sometimes the ordinal numerals (, etc.), as well as , and a small number of other words. Vowels Modern Armenian has six monophthongs. Each vowel phoneme in the table is represented by three symbols. The first is the sounds transcription in the International Phonetic Alphabet (IPA). After that appears the corresponding letter of the Armenian alphabet. The last symbol is its Latin transliteration. Western and other dialects may also have /, /. Consonants The
