Plastic Bertrand takes on European drinks provider (9)
I believe the answer is:
bartender
'drinks provider' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'plastic bertrand takes on european' is the wordplay.
'plastic' indicates anagramming the letters (plastic can mean easily moulded).
'takes on' means one lot of letters goes inside another.
'european' becomes 'e' (abbreviation e.g. EU).
'bertrand' with letters rearranged gives 'bartnder'.
'bartnder' enclosing 'e' is 'BARTENDER'.
Can you help me to learn more?
(Other definitions for bartender that I've seen before include "Server in pub" , "source of 9 [ROUND] ?" , "He serves" , "American serving drinks" , "Liquor salesman" .)
