Short fibre spun (5)
I believe the answer is:
brief
'short' is the definition.
(synonyms)
'fibre spun' is the wordplay.
'spun' indicates an anagram.
'fibre' with letters rearranged gives 'BRIEF'.
(Other definitions for brief that I've seen before include "Terse" , "Provide someone with the facts of the case" , "Fibre (anag.)" , "Solicitor" , "put in the picture" .)
