Lures away from lecherous type of feedback (4)
I believe the answer is:
echo
'feedback' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's a link between them I don't understand?
'lures away from lecherous type' is the wordplay.
'away from' is a deletion indicator.
'type' is an anagram indicator.
'lecherous' with 'lures' taken out is 'cheo'.
'cheo' with letters rearranged gives 'ECHO'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for echo that I've seen before include "The distant sound" , "Trace call" , "from Brussels?" , "Reproduction" , "Imitate -- a nymph" .)
