Joy with members of family ousting extremists (7)
I believe the answer is:
elation
'joy' is the definition.
(I know that elation is a type of joy)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for elation that I've seen before include "Feeling of joy from toenail" , "Euphoria of toenail" , "Feeling of delight or pride" , "Transport" , "Feeling of intense delight" .)
