The Archers have at least one listener! (3)
I believe the answer is:
ear
'least one listener' is the definition.
'ear' can be an answer for 'listener' (body part which hears or listens). I am not sure about the 'least one' bit.
'the archers have' is the wordplay.
'have' indicates a hidden word.
'EAR' is hidden within 'the archers'.
'at' acts as a link.
Can you help me to learn more?
(Other definitions for ear that I've seen before include "one hears" , "Hammer in this" , "Listener in the cornfield" , "Organ involved with balance" , "willingness to listen" .)
