"Not Much Left." Strange title (6)
I believe the answer is:
little
'not much' is the definition.
(synonyms)
'left strange title' is the wordplay.
'left' becomes 'l' (common abbreviation).
'strange' is an anagram indicator.
'title' with letters rearranged gives 'ittle'.
'l'+'ittle'='LITTLE'
(Other definitions for little that I've seen before include "The Battle of ... Bighorn, Custer's last stand" , "part of Stuart in film?" , "petty" , "Self-important authoritarian" , "Peanuts" .)
