Incident in a fine bazaar (6)
I believe the answer is:
affair
'incident' is the definition.
(thesaurus)
'a fine bazaar' is the wordplay.
'a fine' becomes 'af' (I've seen this in other clues).
'bazaar' becomes 'fair' (synonyms).
'af'+'fair'='AFFAIR'
'in' is the link.
(Other definitions for affair that I've seen before include "Concern,matter" , "Clandestine romance" , "Romantic relationship between two unmarried people" , "Former Belgian coin" , "A matter, perhaps of love" .)
