Norma sent off trinkets (9)
I believe the answer is:
ornaments
'trinkets' is the definition.
(I've seen this before)
'norma sent off' is the wordplay.
'off' indicates anagramming the letters.
'norma'+'sent'='normasent'
'normasent' anagrammed gives 'ORNAMENTS'.
(Other definitions for ornaments that I've seen before include "Tree baubles" , "Trinkets" , "Decorations, embellishments" , "Decorates" , "Adornments, decorations" .)
