She loved Narcissus (4)
I believe the answer is:
echo
'she loved narcissus' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for echo that I've seen before include "One who slavishly copies" , "Imitate -- a nymph" , "next to delta" , "Bounced sound" , "repercussion" .)
