Coerce reporters to turn and ascend (10)
I believe the answer is:
pressurise
'coerce' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'reporters to turn and ascend' is the wordplay.
'reporters' becomes 'press' (newspaper reporters).
'to turn' becomes 'u' (a 'U-turn' is a kind of turn).
'and' says to put letters next to each other.
'ascend' becomes 'rise' (rising is a kind of ascending).
'press'+'u'+'rise'='PRESSURISE'
Can you help me to learn more?
(Another definition for pressurise that I've seen is " Attempt to coerce (into doing something)".)
