This work by Bentley Layton is a newly revised, third edition of the standard reference grammar of Coptic in the classical Sahidic dialect. Compared to the previous edition, A Coptic Grammar incorporates new additions and corrections, and retains a full index locorum of examples cited in the grammar. Citations are the backbone of any reference grammar, and this index gives readers immediate access to a grammatical discussion of about three thousand citations of classical Coptic. Especially noteworthy is the extensive use of citations from the celebrated Coptic stylist Shenoute of Atripe.
