Displaced individual denied right to provide further details (9)
I believe the answer is:
expatiate
'denied right to provide further details' is the definition.
I can't judge whether this definition defines the answer.
'displaced individual' is the wordplay.
I cannot quite see how this works, but
'individual' could be 'ex' (ex is a kind of individual) and 'ex' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for expatiate that I've seen before include "Speak in detail (on)" , "write in great detail" , "Elaborate" , "Speak or write at length about subject" , "Speak/write in detail (on)" .)
