She loved Narcissus it's recalled (4)
I believe the answer is:
echo
'she loved narcissus' is the definition.
(I've seen this in another clue)
'it's recalled' is the wordplay.
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'recalled' becomes 'cho' (I am not sure about this - if you are sure you should believe this answer much more).
'e'+'cho'='ECHO'
Can you help me to learn more?
(Other definitions for echo that I've seen before include "Greek nymph, spurned by Narcissus, who pined away until only her voice remained" , "Reiterate" , "Evocation" , "from Brussels?" , "Reflect in Czechoslovakia" .)
