Caught sight of Egyptian tongue (6)
I believe the answer is:
coptic
This clue could be a double definition.
'caught sight of egyptian' is the first definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives occasionally mean the same thing.
'tongue' is the second definition.
(I know that Coptic is a type of Egyptian)
Can you help me to learn more?
(Other definitions for coptic that I've seen before include "Egyptians in the past" , "Sweet; fungus" , "Orthodox Christian church based in Egypt" , "religious language" , "A language of Egypt" .)
