In it the Old Egyptian verbal forms are mostly replaced by periphrases; though the strong roots are often preserved entire, the weaker con9onants and the ~ have- largely or entirely disappeared, so that the language appears as one of biliteral rather than triliteral roots.
The latter acquired the Semitic language imperfectly from their conquerors; they expressed the verbal conjugations by periphrases, mispronounced the consonants, and so changed greatly, the appearance of the vocabulary, which also would certainly contain a large proportion of native nonSemitic roots.
The typical Coptic root thus became biliteral rather than triliteral, and the verb, by means of periphrases, developed tenses of remarkable precision.
