Swift to criticise papers (5)
I believe the answer is:
rapid
'swift' is the definition.
(thesaurus)
'criticise papers' is the wordplay.
'criticise' becomes 'rap' (I've seen this before).
'papers' becomes 'id' (identification papers).
'rap'+'id'='RAPID'
'to' acts as a link.
(Other definitions for rapid that I've seen before include "Showing pace" , "haste" , "Expeditious" , "Happening at great speed" , "Express" .)
