Satirical, lively Scotsman (8)
I believe the answer is:
swiftian
'satirical' is the definition.
(reminiscent of Jonathan Swift, Irish satirist)
'lively scotsman' is the wordplay.
'lively' becomes 'swift' (swift can mean lively or energetic).
'scotsman' becomes 'ian' (common Scottish name).
'swift'+'ian'='SWIFTIAN'
(Other definitions for swiftian that I've seen before include "How like an Irish writer" , "ferociously satirical" .)
