A Coptic Dictionary, pt 1-6

What is here offered represents an entirely new and independent working over of the total available material. Our word-collecting has all been done directly, from the texts ; all those in print have of course been utilized—often after collation with the originals ; so too all unpublished manuscripts, ostraca and inscriptions, to which access could be obtained. The quantity of material used amounts, at a rough estimate, to some 240,000 slips.4 It is hoped that these resources give a sufficient basis for a comprehensive view of the language, in all its dialects and in all aspects of its literature : biblical, patristic and mundane. The total of recorded independent words—ignoring the countless derived forms—is 3,308, whereof some 390 are still of unknown meaning. These are mostly άπαξ λεγάμενα and some are no doubt misread.
