Meaning: ⲧⲁⲙ-, perhaps cognate with the Nobiin ⲧⲁⲙ-, 'to speak (in sleep); wish; guess' + -ⲧⲓ (substantive formant) + -ⲕⲟ, 'to have' + -ⲛ (genitive) + ⲁⲥⲧ-, 'daughter' + -ⲓ (epenthetic?) = 'daughter of Tamtiko' = 'daughter of the one who has a wish/guess'?
The etymology of the name is uknown, but the presence of ⲧ- is suggestive of an Egyptian name, all the more so since Tamoh was a woman. Perhaps ⲧⲁⲙⲱϩ is ⲧⲁϩⲱⲙ, the female variant of ⲡⲁϩⲱⲙ, under the metathesis of the final consonant.
