Required to make a desk (5)
I believe the answer is:
asked
'required' is the definition.
('ask' can be a synonym of 'require')
'make a desk' is the wordplay.
'make' indicates an anagram.
'a'+'desk'='adesk'
'adesk' anagrammed gives 'ASKED'.
'to' is the link.
(Other definitions for asked that I've seen before include "Put a question to" , "Demanded" , "Made a request" , "Enquired; invited" , "Inquired" .)
