Live with son being demoted to supply outlets (5)
I believe the answer is:
exits
'outlets' is the definition.
('exit' can be a synonym of 'outlet')
'live with son being demoted' is the wordplay.
I cannot quite see how this works, but
'son' could be 's' (genealogical abbreviation for son) and 's' is present in the answer.
'being' could be 'ex' (ex is a kind of being) and 'ex' is found in the answer.
The remaining letters 'it' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to supply' is the link.
Can you help me to learn more?
(Other definitions for exits that I've seen before include "Goes out, leaves" , "Withdraws" , "Leaves the stage" , "Departs" , "Ways out" .)
