well...may be you are right.....But knowing the synonyms in different languages and dialects is a great thing
also it's good to make use of the fertility of the coptic language, and not just accepting the foreign words ,even new words like cinema , TV etc...we can use them beside finding a coptic equivalent to them.....languages like chinese and even deutsch use equivalents to the new terms....like in deutsch cinema= kino .....
and by the way i found in a post, someone using ⲉⲛϫⲗⲁⲛⲇ refering to UK (England) , so why he didn't use ⲉⲛⲅⲉⲗⲧⲉⲣⲁ instead, did he use the name of the country as its people call it ? ..... but asking a greek friend , he told me that UK in old greek was " Tin Island " as it was famous for this metal specially for Phoenician . and also the word England means " land of Angles " ( Angles is a name of a tribe lived there)...
what I want to say is that coptic language is very elastic , and unique in the structure of its words , so let's be worthy of knowing it , and resurrecting it as i think what this site for !!
