Not much left and right to turn heads (6)
I believe the answer is:
little
'not much' is the definition.
('little' is the opposite to 'much')
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for little that I've seen before include "Piddling" , "'A . . . . . . knowledge is a dangerous thing'" , "Minor" , "Small or minute" , "The Battle of ... Bighorn, Custer's last stand" .)
