Sterling title, maybe, but it doesn't mean much (6)
I believe the answer is:
little
'it doesn't mean much' is the definition.
The definition suggests a singular noun which matches the answer.
'sterling title maybe' is the wordplay.
'sterling' becomes 'l'.
'maybe' is an anagram indicator.
'title' with letters rearranged gives 'ittle'.
'l'+'ittle'='LITTLE'
'but' is the link.
Can you help me to learn more?
(Other definitions for little that I've seen before include "Teensy-weensy" , "Small in quantity or degree" , "Novel heroine born in the Marshalsea" , "Not big, much or important" , "'A . . . . . . knowledge is a dangerous thing'" .)
