One may need skill interrupting a drunken spree? (9)
I believe the answer is:
bartender
'one may need' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'skill interrupting a drunken spree?' is the wordplay.
'skill' becomes 'art' (both can mean a talent).
'interrupting' indicates putting letters inside.
'a drunken spree?' becomes 'bender' (I've seen this in another clue).
'art' placed inside 'bender' is 'BARTENDER'.
Can you help me to learn more?
(Other definitions for bartender that I've seen before include "Local worker" , "Someone serving drinks" , "Taverner" , "The person doing the drinks" , "server of drinks?" .)
