Armenian orthography reform

The Armenian orthography reform occurred between 1922 and 1924 in Soviet Armenia and was partially reviewed in 1940. Its main features were neutralization of classical etymological writing and the adjustment of phonetic realization and writing.

This orthographic reform is not to be confused or associated with the 13th-century alphabet extension introducing letters ⟨օ⟩ and ⟨ֆ⟩.

The original orthography is now known as the classical orthography (Armenian: դասական ուղղագրութիւն dasakan uġġagrut'yun) and is sometimes referred to as Mashtotsian orthography (մաշտոցեան ուղղագրութիւն), after Mesrop Mashtots, who invented the Armenian alphabet in 405 AD.
