A battle by English head to provide knowledge (9)
I believe the answer is:
awareness
'knowledge' is the definition.
(awareness is a kind of knowledge)
'a battle by english head' is the wordplay.
'battle by' becomes 'war' (I've seen this before. I am not sure about the 'by' bit.**).
'english' becomes 'e' (abbreviation).
'head' becomes 'ness' (ness is a headland).
'a'+'war'+'e'+'ness'='AWARENESS'
'to provide' is the link.
Can you help me to learn more?
(Other definitions for awareness that I've seen before include "understanding" , "Consciousness, sentience" , "Fact of consciousness" , "Consciousness,knowingness" , "State of being conscious" .)
