Live on the edge of NYC playing regular gig in the pub (9)
I believe the answer is:
residency
'gig in the pub' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'live on the edge of nyc playing regular' is the wordplay.
'live' becomes 'reside' (residing is a kind of living).
'on' is a charade indicator (letters next to each other).
'the edge of' suggests removing the centre (I've seen 'edges of' mean this).
'playing regular' becomes 'y' (I can't justify this - if you can you should believe this answer much more).
'nyc' with its middle removed is 'nc'.
'reside'+'nc'+'y'='RESIDENCY'
Can you help me to learn more?
(Other definitions for residency that I've seen before include "circumstance of living in a particular place" , "live-in post" , "Home" , "Fact of living in a place" , "Position in house" .)
