Chaos seen in Times Square (4)
I believe the answer is:
mess
'chaos' is the definition.
(thesaurus)
'in times square' is the wordplay.
'in' indicates a hidden word.
'MESS' is hidden in the letters of 'times square'.
'seen' is the link.
(Other definitions for mess that I've seen before include "State of disorder" , "Where sailors eat" , "Communal dining room" , "dirty and unpleasant" , "Service dining-area" .)
