Every fruit quietly disappearing (4)
I believe the answer is:
each
'every' is the definition.
(synonyms)
'fruit quietly disappearing' is the wordplay.
'fruit' becomes 'peach' (type of fruit).
'quietly' becomes 'p' (p for piano and quiet).
'disappearing' suggests deleting specific letters.
'peach' with 'p' taken away is 'EACH'.
(Other definitions for each that I've seen before include "Every one separately" , "...per head" , "Every single one, person or thing" , "This way for a place" , "Everyone separately" .)
