Wasp, perhaps, to hover next to drink (3,4)
I believe the answer is:
fly half
'wasp perhaps' is the definition.
(rugby position - the Wasps are a rugby team)
'hover next to drink' is the wordplay.
'hover' becomes 'fly' (hover can mean to fly).
'next to' says to put letters next to each other.
'drink' becomes 'half' (I've seen this before).
'fly'+'half'='FLY-HALF'
'to' acts as a link.
(Other definitions for fly half that I've seen before include "Footballer" , "Rugby position" , "Rugby player" , "eg Jonny Wilkinson" .)
