A parent with energy is extraordinary (7)
I believe the answer is:
amazing
'extraordinary' is the definition.
(thesaurus)
'a parent with energy' is the wordplay.
'parent' becomes 'ma' (ma can mean mum or mother).
'with' says to put letters next to each other.
'energy' becomes 'zing' (I've seen this before).
'a'+'ma'+'zing'='AMAZING'
'is' is the link.
(Other definitions for amazing that I've seen before include "Stunning, surprising" , "Filling with wonder, a huge surprise" , "Unbelievable!" , "Very surprising, remarkable" , "Hymn that 'sav'd a wretch like me'?" .)
