Disconnected and receiving no publicity (9)
I believe the answer is:
unplugged
'disconnected' is the definition.
('unplug' can be a synonym of 'disconnect')
'receiving no publicity' is the wordplay.
I cannot quite see how this works, but
'no' could be 'n' (common abbreviation) and 'n' is located in the answer.
'publicity' could be 'plug' (plug is a kind of publicity) and 'plug' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for unplugged that I've seen before include "Performed acoustically rather than with amplification" , "without any electronic devices" , "Acoustic" , "Disconnected" .)
