All I cry out is ecstatic (7)
I believe the answer is:
lyrical
'ecstatic' is the definition.
(thesaurus)
'all i cry out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'all'+'i'+'cry'='allicry'
'allicry' with letters rearranged gives 'LYRICAL'.
'is' is the link.
(Other definitions for lyrical that I've seen before include "carried away" , "it can be waxed" , "Song-like, imaginative or expressive" , "To wax - is to enthuse" , "We may wax this" .)
