Knowledge shown by Russell, who's covering battle at Scottish lake (9)
I believe the answer is:
awareness
'knowledge' is the definition.
(awareness is a kind of knowledge)
'russell who's covering battle at scottish lake' is the wordplay.
I cannot quite see how this works, but
'battle' could be 'war' (armed conflict) and 'war' is found within the answer.
'russell' could be 'ae' (I've seen this in other clues) and 'ae' is located in the remaining letters.
'scottish lake' could be 'ness' (I've seen this in another clue) and 'ness' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'shown by' acts as a link.
Can you help me to learn more?
(Other definitions for awareness that I've seen before include "Consciousness,knowingness" , "Knowledge or consciousness" , "State of being conscious" , "Mindfulness, consciousness" , "Grasp" .)
