Cry, having registered scuffle (5)
I believe the answer is:
brawl
'scuffle' is the definition.
(I've seen this before)
'cry having registered' is the wordplay.
'cry' becomes 'bawl' (synonyms).
'having' indicates putting letters inside.
'registered' becomes 'R' (abbreviation, as in registered trademark).
'bawl' placed around 'r' is 'BRAWL'.
(Other definitions for brawl that I've seen before include "I'd punt for a learned person" , "Fracas" , "Affray" , "Noisy crowd fight" , "Quarrel noisily" .)
