Classical Armenian
Classical Armenian (Armenian:գրաբար, grabar, Western Armenian krapar, meaning "literary [language]"; also Old Armenian or Liturgical Armenian) is the oldest attested form of the Armenian language. It was first written down at the beginning of the 5th century, and all Armenian literature from then through the 18th century is in the Grabar Armenian language. Many ancient manuscripts originally written in Ancient Greek, Persian, Hebrew, Syriac and Latin survive only in their Armenian translation. Classical Armenian continues to be the liturgical language of the Armenian Apostolic Church and is often learned by Biblical, Intertestamental, and Patristic scholars dedicated to textual studies. Classical Armenian is also important for the reconstruction of the Proto-Indo-European language.
