Leave fruit after daughter is a little quiet (9)
I believe the answer is:
disappear
'leave' is the definition.
(I've seen this before)
'fruit after daughter is a little quiet' is the wordplay.
'fruit' becomes 'pear' (pear is a kind of fruit).
'after' says to put letters next to each other.
'daughter' becomes 'd' (genealogical abbreviation).
'little' means to remove the last letter (the word is not quite complete).
'quiet' becomes 'pp' (music symbol for 'pianissimo').
'pp' with its final letter taken away is 'p'.
'd'+'is'+'a'+'p'='disap'
'pear' put after 'disap' is 'DISAPPEAR'.
(Other definitions for disappear that I've seen before include "Escape" , "Vanish, cease to be visible" , "Fade out" , "Go missing" , "suddenly depart" .)
