Coptic = Egyptian

            yes, Coptic & Egyptian mean exactly the same thing ( synonyms) .

the Greeks gave the name : " Aiguptos " to Egypt .

 why ? let me tell you.

at a certain  time before Alexander the Great, probably the 9th century BC,

when the Greek civilization began to flourish,

 Egypt was a great country , much more civilized than the Greeks. at that time 

Hut-ka-Ptah, was the name of the  famous temple of the god Ptah , at "Memphis" the famous Egyptian city,

(literally the "house of the ka/spirit of Ptah").

This name was borrowed by the Greeks  at that time , but they've pronounced it differently, as a matter of fact.

 It occurred  in Mycenaean Greek as "a-ku-pi-ti-yo", later Classical Greek aiguptos. In Akkadian cuneiform documents it occurred  as xi-ku-up-ta-ax (Khi-ku-ptakh) and later it was used instead of, or as the name of " Memphis ".

As most of the times , when you hear the name of  big cities or capitals , you immediately

remember the country itself , so the Greeks gave the name of the most important city which was

known by the name of its famous temple now  " aiguptos " ,  to the whole country.

This indicates that the name of the temple was being used for the name of the city

 and later for the name of the country.

 (The /t/ on the end of Hut fell off in pronunciation, much like the ta-marbutah of Arabic.)

                        ================================================

          when the Arabs came to Egypt the heard that name also

Aiguptoc  , as the Greek language , at that time , was the international  cultural language

& was known allover the Mediterranean  countries & the old world,  as English now .

the Arabs don't have the suffix : " os " , also they don't have the hard letter : G , as in the word

" Good " in English,

they only have the soft  letter : G ,  the same as soft  letter " G ", in English

as in the word : "gentle" , for  example.

so the closest pronunciation of the that letter to their tongue is :  " K " or " Q "  which

corresponds to the letter "Quaf " in Arabic.

so , by omitting the prefix : "Ai " 

                     and the suffix  " os " , &  pronouncing the hard " G " as   " Q ",

it became : qypt  , or  kypt , which has been further  modified to"  kopt "  (Copte )

by the  European tongue ( like  :  Italian , French , English , etc ........)   .

So, Coptic = Egyptian , it's easy you know ? !
