One living abroad losing right to wander about (9)
I believe the answer is:
expatiate
'wander about' is the definition.
I can't tell whether this defines the answer.
'one living abroad losing right' is the wordplay.
'one living abroad' becomes 'expatriate' (someone living abroad).
'losing' suggests deleting specific letters.
'right' becomes 'r' (common abbreviation).
'expatriate' with 'r' removed is 'EXPATIATE'.
'to' is the link.
Can you help me to learn more?
(Other definitions for expatiate that I've seen before include "Make detailed speech" , "Go on at length" , "Speak or write at length about subject" , "Speak/write in detail (on)" , "Speak in detail (on)" .)
