Live well at the back of beyond (5)
I believe the answer is:
dwell
'live' is the definition.
(to live/dwell somewhere)
'well at the back of beyond' is the wordplay.
'at' means one lot of letters go next to another (I've seen this in other clues).
'the back of' says to take the final letters.
The final letter of 'beyond' is 'd'.
'well' after 'd' is 'DWELL'.
(Other definitions for dwell that I've seen before include "Focus attention (on)" , "Harp" , "Hang out" , "Lodge" , "Settle" .)
