My Arabic / Masri is bad, but I agree, some of these names are Kamitized forms of Greek names - Arete (Ⲁⲣⲏⲧⲉ) means virtue in Greek, and Nous (from Ⲫⲁⲛⲟⲩⲥ) means mind, while I can't find a similar meaning in Coptic.
I also find that some of the meanings that have been given are Christianized - for example Ⲁⲡⲁϩⲱⲣ ⲛⲉⲙ Ⲁⲡⲁⲛⲟⲩⲃ. It is true that Abanoub could mean something related to gold, but because I have found the names Ⲁⲡⲁϩⲱⲣ, Ⲁⲡⲁⲛⲟⲩⲃ, ⲛⲉⲙ Ⲁⲡⲁⲙⲟⲩⲛ, it is clear that ⲁⲡⲁ- is modifying Ϩⲱⲣ, Ⲁⲛⲟⲩⲃ, ⲛⲉⲙ Ⲁⲙⲟⲩⲛ, and these probably represent pre-Christian Coptic names. Still, I do not know the meaning of ⲁⲡⲁ-.
So, whoever sees this, where did you get your names and meaning? Do you know people with these names, in person? If not, what is your source?
I am constructing a page for the Wiki that lists all known Coptic names.
