When news is on usually officer listens (7)
I believe the answer is:
attends
'listens' is the definition.
(attending is a kind of listening)
'when news is on usually officer' is the wordplay.
'when news is on usually' becomes 'at ten' (eg BBC News at d0).
'officer' becomes 'ds' (I am not sure about this - if you are sure you should believe this answer much more).
'atten'+'ds'='ATTENDS'
Can you help me to learn more?
(Other definitions for attends that I've seen before include "to listen carefully" , "Listens" , "Heeds" , "Appears" , "ministers" .)
