Not involved in fight so not charged (7)
I believe the answer is:
neutral
'charged' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for neutral that I've seen before include "Impartial; colourless" , "Not siding with any parties to a dispute" , "Not siding with any party" , "Impartial, non-aligned" , "without any charge" .)
