Spirit bottles a beneficial thing (4)
I believe the answer is:
gain
'beneficial thing' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'spirit bottles a' is the wordplay.
'spirit' becomes 'gin' (I've seen this before).
'bottles' indicates putting letters inside ('bottle' can mean to contain).
'gin' placed around 'a' is 'GAIN'.
Can you help me to learn more?
(Other definitions for gain that I've seen before include "Advance" , "Profit; acquire" , "Obtain; earn" , "Win" , "Increase; secure" .)
