Brought up rule with listeners (6)
I believe the answer is:
reared
'brought up' is the definition.
(rearing is a kind of bringing up)
'rule with listeners' is the wordplay.
'rule' becomes 'r' (legal abbreviation).
'with listeners' becomes 'eared' (having ears - things that listen).
'r'+'eared'='REARED'
(Other definitions for reared that I've seen before include "upright" , "Fostered, brought up" , "Trained" , "Provided and cared for during childhood" , "Brought up, nurtured" .)
