More than one listener oddly ignored legal risk (4)
I believe the answer is:
ears
'more than one listener' is the definition.
'oddly ignored legal risk' is the wordplay.
'oddly ignored' means one should take alternating letters.
'legal'+'risk'='legalrisk'
The alternate letters of 'legalrisk' are 'EARS'.
(Other definitions for ears that I've seen before include "Organs for 7 down" , "Spikes of corn" , "Corn; organs" , "Listening organs" , "Heads of corn" .)
