Cry loudly about ringleader causing noisy fight (5)
I believe the answer is:
brawl
'noisy fight' is the definition.
(I've seen this in another clue)
'cry loudly about ringleader' is the wordplay.
'cry loudly' becomes 'bawl' (I've seen this before).
'about' indicates putting letters inside.
'ringleader' becomes 'r' (first letter of ring).
'bawl' going around 'r' is 'BRAWL'.
'causing' acts as a link.
(Other definitions for brawl that I've seen before include "squabble" , "Rough, noisy fight" , "Scuffle, unseemly fight" , "Rowdy fight" , "Abounding" .)
