Entangled fibre not lasting very long (5)
I believe the answer is:
brief
'not lasting very long' is the definition.
I can't tell whether this defines the answer.
'entangled fibre' is the wordplay.
'entangled' is an anagram indicator.
'fibre' with letters rearranged gives 'BRIEF'.
Can you help me to learn more?
(Other definitions for brief that I've seen before include "Provide someone with the facts of the case" , "Fibre (anag.)" , "Short - work for counsel" , "Document stating the facts of a legal case" , "Short or concise" .)
