Let bachelor nurse beer, getting round (6)
I believe the answer is:
enable
'let' is the definition.
(I've seen this in another clue)
'bachelor nurse beer getting round' is the wordplay.
'bachelor' becomes 'B' (abbreviation e.g. BA=Bachelor of Arts).
'nurse' becomes 'EN' (abbreviation for enrolled nurse).
'beer' becomes 'ale' (type of beer).
'getting round' is an insertion indicator.
'en'+'ale'='enale'
'b' inserted inside 'enale' is 'ENABLE'.
(Other definitions for enable that I've seen before include "Make possible using baleen" , "Authorise" , "Allow" , "Activate" , "Permit or facilitate" .)
