A bed rather dishevelled, ragged (10)
I believe the answer is:
threadbare
'ragged' is the definition.
(I've seen this before)
'a bed rather dishevelled' is the wordplay.
'dishevelled' is an anagram indicator.
'a'+'bed'+'rather'='abedrather'
'abedrather' with letters rearranged gives 'THREADBARE'.
(Other definitions for threadbare that I've seen before include "poor" , "deprived of nap" , "Shabby" , "Hackneyed" , "Well-worn" .)
