Power couple, losing money, flare up again (8)
I believe the answer is:
reignite
'losing money flare up again' is the definition.
I can't tell whether this defines the answer.
'power couple' is the wordplay.
'power' becomes 'reign' (reign can mean time in power).
'couple' becomes 'ite' (I can't justify this - if you can you should believe this answer much more).
'reign'+'ite'='REIGNITE'
Can you help me to learn more?
(Other definitions for reignite that I've seen before include "torch again" , "Set fire to - again" , "What one may do to old controversy" , "Once again, send up" , "Kindle again" .)
