Give false impression female will find confidence (6)
I believe the answer is:
belief
'confidence' is the definition.
(I've seen this before)
'give false impression female' is the wordplay.
'give false impression' becomes 'belie' (belie can mean to disguise or distort).
'female' becomes 'f' (abbreviation).
'belie'+'f'='BELIEF'
'will find' is the link.
(Other definitions for belief that I've seen before include "Creed or opinion" , "Principle accepted without proof" , "Faith, doctrine" , "Conviction, faith" , "Tenet, creed" .)
