Displaced individual denied right to provide further details (9)

Ross

I believe the answer is:

expatiate

I'm a little stuck... Click here to teach me more about this clue!

'denied right to provide further details' is the definition.
I can't tell whether this defines the answer.

'displaced individual' is the wordplay.
I cannot really understand how this works, but
'individual' could be 'ex' (ex is a kind of individual) and 'ex' is located in the answer.
This explanation may well be incorrect...

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)" .)
