Copy Spain and Switzerland, love (4)
I believe the answer is:
echo
'copy' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for echo that I've seen before include "Return of sound waves" , "Reflected radar beam" , "one catches on the rebound?" , "Reproduction" , "Mimic" .)
