Game for a drink after hard work (9)
I believe the answer is:
hopscotch
'game' is the definition.
(hopscotch is a kind of game)
'a drink after hard work' is the wordplay.
'a drink' becomes 'scotch' (Scotch is an example**).
'after' means one lot of letters go next to another.
'hard' becomes 'h'.
'work' becomes 'op' (abbreviation for opus).
'h'+'op'='hop'
'scotch' put after 'hop' is 'HOPSCOTCH'.
'for' acts as a link.
(Other definitions for hopscotch that I've seen before include "Playground game" , "childish amusement" , "Children's game with squares on ground" , "Jumping game" , "kids jump about in it" .)
