Society, say, mad and divided into sections (9)
I believe the answer is:
segmental
'divided into sections' is the definition.
I can't judge whether this definition defines the answer.
'society say mad' is the wordplay.
'society' becomes 's' (common abbreviation in names of organisations).
'say' becomes 'eg'.
'mad' becomes 'mental'.
's'+'eg'+'mental'='SEGMENTAL'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for segmental that I've seen before include "As, say, Orange" , "Composed of distinct parts" .)
