Lean on the papers (5)
I believe the answer is:
press
I believe this is a double definition.
'lean on' is the first definition.
(thesaurus)
'the papers' is the second definition.
(I've seen this before)
(Other definitions for press that I've seen before include "newspapermen?" , "Weigh" , "Cupboard for storing clothes" , "Newspaper industry" , "Squeeze out (juice/oil)" .)
