Select a beer, taking work over (7)
I believe the answer is:
appoint
'select' is the definition.
(I've seen this in another clue)
'a beer taking work over' is the wordplay.
'beer' becomes 'pint' (beer is typically served by the pint).
'taking' indicates putting letters inside.
'work over' becomes 'po' (I can't justify this - if you can you should believe this answer much more).
'pint' placed around 'po' is 'ppoint'.
'a'+'ppoint'='APPOINT'
Can you help me to learn more?
(Other definitions for appoint that I've seen before include "Ordain" , "Fix" , "Assign job to (someone)" , "Delegate" , "Assign to a post" .)
