Fruit found in bed after almost thirty days (7)
I believe the answer is:
apricot
'fruit' is the definition.
(type of fruit)
'bed after almost thirty days' is the wordplay.
'bed' becomes 'cot' (cot is a type of bed).
'after' is a charade indicator (letters next to each other).
'almost' means to remove the last letter (almost the whole word is kept).
'thirty days' becomes 'april' (I've seen this before).
'april' with its final letter taken off is 'apri'.
'cot' put after 'apri' is 'APRICOT'.
'found in' acts as a link.
(Other definitions for apricot that I've seen before include "I part co with the fruit" , "Orange-coloured fruit" , "Soft, peach-like fruit" , "A fruit-tree" , "Fruit resembling a peach" .)
