Soft drink without fruit (5)
I believe the answer is:
apple
'fruit' is the definition.
(I know that apple is a type of fruit)
'soft drink without' is the wordplay.
'soft' becomes 'pp' (musical abbreviation for pianissimo).
'drink' becomes 'ale' (type of beer).
'without' indicates putting letters inside.
'pp' going into 'ale' is 'APPLE'.
(Other definitions for apple that I've seen before include "Crab, cooking or eating fruit" , "German fruity dessert" , "Fruit with firm white flesh" , "Tree of the rose family" , "Common fruit" .)
