Resisting skilful Scot is included (7)
I believe the answer is:
defiant
'resisting' is the definition.
(thesaurus)
'skilful scot is included' is the wordplay.
'skilful' becomes 'deft' (deft means skilful).
'scot' becomes 'ian' (Scottish given name).
'is included' is an insertion indicator.
'deft' enclosing 'ian' is 'DEFIANT'.
(Other definitions for defiant that I've seen before include "Fainted, being rebellious" , "Mutinous" , "Insubordinate" , "Boldly resisting" , "Refusing to comply" .)
