ϣⲟⲩⲉ vs ⲕⲟⲩϫⲓ

[ⲧⲁⲛⲓⲉⲗ ⲅⲓⲣⲅⲓⲥ]

I came across both words and it seems that they both refer to small things. Is there a difference in the actual meanings of the words or could they be used interchangeably?

[ⲡⲓⲙⲟⲩⲓ]

ⲛⲟϥⲣⲓ ⲧⲁⲛⲓⲉⲗ,

ϣⲟⲩⲉ is a Sahidic Coptic word, while ⲕⲟⲩϫⲓ (ⲕⲟⲩⲓ in Sahidic) is a Bohairic one.

ⲟⲩϫⲁⲓ,
ⲡⲓⲙⲟⲩⲓ
