Disturbance caused by father when ringing around (6)
I believe the answer is:
fracas
'disturbance' is the definition.
(thesaurus)
'father when ringing around' is the wordplay.
'father' becomes 'fr'.
'when' becomes 'as'.
'ringing' is an insertion indicator.
'around' becomes 'ca' (circa**).
'as' placed around 'ca' is 'acas'.
'fr'+'acas'='FRACAS'
'caused by' acts as a link.
(Other definitions for fracas that I've seen before include "Uproar - brawl" , "Melee" , "Skirmish" , "Bust-up" , "Affray" .)
