Eccentric’s class dividing class on both sides (6)
I believe the answer is:
cranks
'eccentric's class dividing class on both sides' is the definition.
I can't judge whether this definition defines the answer.
'class dividing class on both sides' is the wordplay.
'class' becomes 'rank' (I have seen 'Social class ' mean 'rank' so perhaps 'class' could also mean 'rank').
'dividing' indicates putting letters inside (inserted letters divide the word).
'on both sides' says to hollow out the word (remove centre letters) (the left and right sides of the word are used).
'class' with its middle removed is 'cs'.
'rank' put into 'cs' is 'CRANKS'.
Can you help me to learn more?
(Other definitions for cranks that I've seen before include "people irascible in America" , "Drugs" , "People with crazy ideas" .)
