Meaning: ⲙⲟⲩϣⲉ-, perhaps cognate with the Nobiin ⲙⲟⲩϣⲉ, 'longing, yearning' + -ⲛ (genitive) + ⲁⲥⲧ-, 'daughter' + -ⲓ (epenthetic) = 'daughter of Moushe' = 'daughter of «yearning»'.
It is uncertain whether this is a proper name or another kind of formation. Alternatives include 'daughter of Moushe', 'asti of Moushe' (title + toponym), 'asti of Moushe' (teritorrial unit).
