A rating possibly announced for battery (7)
I believe the answer is:
assault
This might be a double definition.
'a rating' is the first definition.
(thesaurus)
'announced for battery' is the second definition.
'assault' can be an answer for 'battery' (synonyms). I am not certain of the 'announced for' bit.
'possibly' acts as a link.
Can you help me to learn more?
(Other definitions for assault that I've seen before include "Attack suddenly" , "Attack violently" , "Sort of course" , "set about" , "Lash" .)
