Request contents of basket (3)
I believe the answer is:
ask
'request' is the definition.
('ask' can be a synonym of 'request')
'contents of basket' is the wordplay.
'contents of' indicates a hidden word.
'ASK' is hidden within 'basket'.
(Other definitions for ask that I've seen before include "Something demanded" , "Invite (to a party)" , "Pose" , "Make enquiry" , "Request, invite" .)
