Daughter is young girl showing fire (7)
I believe the answer is:
dismiss
'fire' is the definition.
('dismiss' can be a synonym of 'fire')
'daughter is young girl' is the wordplay.
'daughter' becomes 'dis' (I've seen this in other clues).
'is young girl' becomes 'miss' (I've seen this before).
'dis'+'miss'='DISMISS'
'showing' is the link.
(Other definitions for dismiss that I've seen before include "Reject, send away" , "Fire - cashier" , "military order" , "Throw out" , "Sack - cashier" .)
