Fruit drink very quietly swallowed (5)
I believe the answer is:
apple
'fruit' is the definition.
(I know that apple is a type of fruit)
'drink very quietly swallowed' is the wordplay.
'drink' becomes 'ale' (type of beer).
'very quietly' becomes 'pp' (musical abbreviation for pianissimo).
'swallowed' is an insertion indicator.
'ale' enclosing 'pp' is 'APPLE'.
(Other definitions for apple that I've seen before include "One a day keeps the doctor away" , "Pomaceous fruit" , "Fruit used in cider" , "Delight (of one's eye)" , "Fruit that's Big in the US" .)
