Silly advocate dropping note on egg and fruit (7)
I believe the answer is:
avocado
'fruit' is the definition.
(avocado is a kind of fruit)
'silly advocate dropping note on egg' is the wordplay.
I cannot quite understand how this works, but
'note' could be 'do' (musical note, as in do-re-mi) and 'do' is found in the answer.
'on' could be 'o' (I've seen this in other clues) and 'o' is found in the answer.
This may be the basis of clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for avocado that I've seen before include "Tropical tree - edible green-skinned fruit" , "Are mostly outspoken party getting" , "Greenish-colour" , "Light green colour" , "one's stoned?" .)
