Sense a battle with European head (9)
I believe the answer is:
awareness
'sense' is the definition.
(thesaurus)
'a battle with european head' is the wordplay.
'battle with' becomes 'war' (I've seen this before. I am not sure about the 'with' bit.).
'european' becomes 'E' (abbreviation e.g. EU).
'head' becomes 'ness' (ness is a headland).
'a'+'war'+'e'+'ness'='AWARENESS'
Can you help me to learn more?
(Other definitions for awareness that I've seen before include "Knowing" , "Perception" , "Grasp" , "Consciousness,knowingness" , "Knowledge (of a fact)" .)
