Get nurses behind surgery high on gas (6)
I believe the answer is:
bubbly
'high on gas' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'get nurses behind surgery' is the wordplay.
'get' becomes 'buy' (buying is a kind of getting).
'nurses' means one lot of letters goes inside another (nurse can mean to hold onto or harbour).
'behind surgery' becomes 'bbl' (I can't explain this - if you can you should give a lot more credence to this answer).
'buy' enclosing 'bbl' is 'BUBBLY'.
Can you help me to learn more?
(Other definitions for bubbly that I've seen before include "lively" , "Champers" , "Drink" , "Effervescent" , "Informal champagne" .)
