Requested a new desk (5)
I believe the answer is:
asked
'requested' is the definition.
('ask' can be a synonym of 'request')
'a new desk' is the wordplay.
'new' indicates anagramming the letters.
'desk' is an anagram of 'sked'.
'a'+'sked'='ASKED'
(Other definitions for asked that I've seen before include "Demanded" , "Enquired; invited" , "Questioned" , "Inquired" , "Put a question to" .)
