Hi,
The entry for ϩⲩⲡⲟⲑⲉⲥⲓⲥ (TLA lemma no. C11230) gives three Sahidic spellings, one of which is ⲑⲩⲡⲟⲑⲏⲥⲓⲥ. I can't see the context of this attestation to check but it may be ⲧ- fem. sing. definite article + ϩⲩⲡⲟⲑⲏⲥⲓⲥ. If so, the definite article should be removed leaving ϩⲩⲡⲟⲑⲏⲥⲓⲥ. It seems, looking at the usage examples, that (ϩ)ⲩⲡⲟⲑⲉⲥⲓⲥ is treated as both a masculine and feminine noun.
Thanks,
Ambrose
