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.
