French in grotto round lake: area surrounded (7)
I believe the answer is:
enclave
'french in grotto round' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for enclave that I've seen before include "Enclosed piece of territory" , "Part of country surrounded by foreign territory" , "Isolated cultural group" , "Isolated territory enclosed by valence" , "Territory enclosed within another one" .)
