Fruit pair stupidly put on bed (7)
I believe the answer is:
apricot
'fruit' is the definition.
(apricot is a kind of fruit)
'pair stupidly put on bed' is the wordplay.
'stupidly' is an anagram indicator.
'put on' means one lot of letters go next to another.
'bed' becomes 'cot' (cot is a kind of bed**).
'pair' is an anagram of 'apri'.
'apri'+'cot'='APRICOT'
(Other definitions for apricot that I've seen before include "A fruit-tree" , "Luscious fruit" , "Rip coat (anag) - fruit" , "Orange fruit" , "Orange-yellow fruit in plum family" .)
