This may be a variant of the name Ionnga (Nam 202509) resulting from the following alternations: ⲓⲟⲛⳟⲓ > ⲓⲟⲛⲅⲓ > ⲉⲓⲟⲅⲅⲓ. Note, however, that the regressive assimilation of ⲛ+ⲅ > ⲅⲅ is not known otherwise. Alternatively, this may be a combinative name consisting of ⲉⲓⲟ-, probably cognate with the Nobiin ⲓⲟ-, 'mother; my mother' + -ⲛ (genitive) + ⲅⲓ-, '(maternal) uncle' = 'uncle of mother; maternal uncle?'
Meaning: ⲉⲓⲟ-, probably cognate with the Nobiin ⲓⲟ-, 'mother; my mother' + -ⲛ (genitive) + ⲙⲓⲛⲛⲉ-, perhaps cognate with the Nobiin ⲙⲓⲛⲉ, 'dove' = 'the dove of mother'.
Meaning: perhaps deriving from (ⲉ)ⲓ-, 'to know', or ⲉⲓ-, 'hand', or ⲉⲓⲗ-, 'to say' + ⲟⲩ (substantive formant?) = 'the one who knows/says' or 'the hand'?
Meaning: If this indeed is a Blemmyan name, it should probably be analsed as ⲉⲓⲟⲩ- < ⲓⲟⲩ-, nominative sing. marker + ⲗⲉⲡⲁ, perhaps cognate with the Bedauye 'réba', 'mountain, hill' = 'the mountain'.
Othewise, it may be a Nubian name with the following etymology: ⲉⲓⳣ-, ⲉⲓⲟⲩ-, 'grain, wheat' / ⲉⲗ̄ⲗⲉ-, 'wheat' + ⲉⲡ-, 'take, receive, put?' + -ⲁ (predicative) = 'the one who takes grain of wheat'. This, however, seems less likely.
