Person living abroad has no right to go on and on (9)
I believe the answer is:
expatiate
'person living abroad has no' is the definition.
I can't judge whether this definition defines the answer.
'right to go on and on' is the wordplay.
I cannot really see how this works, but
'on' could be 'at' (I've seen this in other clues) and 'at' is found within the answer.
'right' could be 'expiate' (expiating is a kind of righting) and 'expiate' is present in the remaining letters.
No letters remain.
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)" , "Make detailed speech" , "Elaborate" , "Give details" , "Speak or write at length about subject" .)
