Cover provider now more confident (7)
I believe the answer is:
insurer
'cover provider' is the definition.
'insurer' can be an answer for 'provider' (I have seen 'Provider of cover ' mean 'insurer' so perhaps 'provider' could also mean 'insurer'). I'm unsure of the 'cover' bit.
'now more confident' is the wordplay.
'now' becomes 'in' (I can't explain this - if you can you should believe this answer much more).
'more confident' becomes 'surer' ('sure' can be similar in meaning to 'confident').
'in'+'surer'='INSURER'
Can you help me to learn more?
(Other definitions for insurer that I've seen before include "One offering policy for risk" , "Saga?" , "Provider of a security policy" , "one will provide cover" , "Underwriter, risk taker" .)
