Daughter is ecstatic making protest (7)
I believe the answer is:
dissent
'protest' is the definition.
('dissent' can be a synonym of 'protest')
'daughter is ecstatic' is the wordplay.
'daughter' becomes 'dis' (I've seen this in other clues).
'is ecstatic' becomes 'sent' (I've seen this in other clues).
'dis'+'sent'='DISSENT'
'making' is the link.
(Other definitions for dissent that I've seen before include "Express disagreement" , "Opposition" , "Nonconformity" , "Difference of opinion - snidest (anag)" , "Raise objections" .)
