Fruit drinks including pop devoid of content (6)
I believe the answer is:
apples
'fruit' is the definition.
(I've seen this before)
'drinks including pop devoid of content' is the wordplay.
'drinks' becomes 'ales' (I've seen this before).
'including' means one lot of letters goes inside another.
'pop devoid of content' becomes 'pp' (I can't explain this - if you can you should believe this answer much more).
'ales' going around 'pp' is 'APPLES'.
Can you help me to learn more?
(Other definitions for apples that I've seen before include "''The silver ... of the moon, / The golden ... of the sun'' (W B Yeats)" , "Russets, pippins etc" , "PS, leap up for the fruit" , "Divinely influenced" , "Loud sharp cry" .)
