Provoke current lover (7)
I believe the answer is:
inflame
'provoke' is the definition.
(inflaming is a kind of provoking)
'current lover' is the wordplay.
'current' becomes 'in' (I've seen this in other clues).
'lover' becomes 'flame' (I've seen this in other clues).
'in'+'flame'='INFLAME'
(Other definitions for inflame that I've seen before include "Intensify, aggravate" , "Provoke to anger" , "Incite" , "Be provocative" , "Provoke; aggravate" .)
