Correction : of ⲛⲟϥⲣⲓ ϣⲁⲓ:
Those who try to speak Coptic use a wrong expression which is Ⲛⲟϥⲣⲓ ϣⲁⲓ to mean “happy feast”.
But this is a wrong expression because it does not consist of a an adjective and a noun which express the required meaning, but it consists of two nouns in juxtaposition.
And the word ⲛⲟϥⲣⲓ is not an adjective which means “happy”, but it is a feminine noun which means “good, profit, advantage. So it is a meaningless expression.
