Hearsay includes listener (3)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
ear
'listener' is the definition.
(I've seen this before)
'hearsay includes' is the wordplay.
'includes' indicates a hidden word.
'EAR' can be found hidden inside 'hearsay'.
(Other definitions for ear that I've seen before include "Hammer in this" , "Lend one and listen" , "Shell-like; corn" , "cut" , "Seed-bearing part of wheat" .)
