Parent, say, ignoring rule, gets ecstasy (7)
I believe the answer is:
elation
'ecstasy' is the definition.
(I've seen this before)
'parent say ignoring rule' is the wordplay.
'parent say' becomes 'relation' (parent is a kind of relation).
'ignoring' is a deletion indicator.
'rule' becomes 'r' (legal abbreviation).
'relation' with 'r' taken out is 'ELATION'.
'gets' is the link.
(Other definitions for elation that I've seen before include "Transport" , "Euphoria of toenail" , "Feeling of intense delight" , "Great happiness and exhilaration" , "Feeling of joy and pride" .)
