One way of seeing action is to have a row (11)
I believe the answer is:
altercation
'a row' is the definition.
(altercation is a kind of row)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for altercation that I've seen before include "Squabble" , "Noisy quarrel" , "Noisy disagreement" , "Rattle a coin (anag) - row" , "difference" .)
