Coptic Pronunciation Reform

Coptic pronunciation reform since 1850 has resulted in two major shifts in the use of Bohairic, the dialect of Coptic which is used as the liturgical language of the present-day Coptic Orthodox Church. The two traditions of pronunciation in contemporary use arise from two successive reforms in the 19th and 20th centuries:

• the "reformed pronunciation" or "Greco-Bohairic pronunciation", originally mandated by Pope Cyril IV (1854–1861), models the pronunciation of Coptic letters after their equivalents in Modern Greek.
• the "Old Bohairic pronunciation" aims to reconstruct the pronunciation as it was before this reform.
