Document about papers under paperweight? (9)
I believe the answer is:
depressed
'under paperweight?' is the definition.
'document about papers' is the wordplay.
'document' becomes 'deed' (deed is a kind of document).
'about' is an insertion indicator.
'papers' becomes 'press' (I've seen this before**).
'deed' placed around 'press' is 'DEPRESSED'.
(Other definitions for depressed that I've seen before include "Poverty-stricken" , "Downhearted" , "showing the blues" , "dispirited" , "Having been pushed down" .)
