Some cauliflower is not right or left (6)
I believe the answer is:
floret
'some cauliflower' is the definition.
The definition suggests a singular noun which matches the answer.
'not right or left' is the wordplay.
'not right' is an anagram indicator.
'or'+'left'='orleft'
'orleft' with letters rearranged gives 'FLORET'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for floret that I've seen before include "Part of a cauliflower or broccoli head" , "Small flower" , "Broccoli stem" , "Piece of broccoli" , "Part of cauli head" .)
