Rude to change sides for status (5)
I believe the answer is:
class
'status' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for class that I've seen before include "Group - style" , "pupils?" , "Teaching group" , "Form; stylishness" , "People having the same social or economic status" .)
