Source: Webster's dictionaryHence it is unclear why the word should have entered Arabic with an initial t, which would have required the word to be grammatically feminine (i.e. Sahidic: *ⲧⲉⲙⲥⲁϩ ; Bohairic: *ϯⲉⲙⲥⲁϩ ). Source: Internet
However, it was not until Shenoute that Coptic became a fully standardized literary language based on the Sahidic dialect. Source: Internet
For example, both Sahidic and Bohairic use the word ebenos, which was taken directly from Greek ἔβενος main "ebony", originally from Egyptian hbny. Source: Internet
In Sahidic, syllable boundary may have been marked by a supralinear stroke. Source: Internet
It should be noted, however, that Coptic ⲉⲙⲥⲁϩ is grammatically masculine and hence would have been vocalised pemsaḥ or bemsaḥ (Sahidic: ⲡⲉⲙⲥⲁϩ ; Bohairic: ⲡⲓⲉⲙⲥⲁϩ ). Source: Internet
Some Egyptian syllables had sonorants but no vowels; in Sahidic, these were written in Coptic with a line above the entire syllable. Source: Internet
