Calls for some desks and counters (4)
I believe the answer is:
asks
'calls for' is the definition.
('ask' can be a synonym of 'call for')
'some desks and counters' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'counters' shows that the letters should be reversed in order (I've seen 'counter' mean this).
'sksa' is hidden in the letters of 'desks and'.
'sksa' in reverse letter order is 'ASKS'.
(Other definitions for asks that I've seen before include "Inquiries" , "is curious" , "Invites; enquires" , "Requests information about" , "Begs" .)
