She has complete confidence (5)
I believe the answer is:
faith
This might be a double definition.
'she' is the first definition.
'complete confidence' is the second definition.
'faith' can be an answer for 'confidence' (I've seen this before). I'm unsure of the 'complete' bit.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for faith that I've seen before include "A woman" , "Strong belief in a supernatural power" , "'..... will move mountains'" , "religion" , "Total trust" .)
