Upturn after papers united in force (10)
I believe the answer is:
pressurise
'force' is the definition.
I know nothing about this answer so I can't tell whether this works.
'upturn after papers united' is the wordplay.
'upturn' becomes 'rise' (I've seen this in another clue).
'after' says to put letters next to each other.
'papers' becomes 'press' (the newspaper industry).
'united' becomes 'U' (abbreviation).
'press'+'u'='pressu'
'rise' after 'pressu' is 'PRESSURISE'.
'in' acts as a link.
Can you help me to learn more?
(Another definition for pressurise that I've seen is " Attempt to coerce (into doing something)".)
