Sort of chop artist fed to shrew (6)
I believe the answer is:
karate
'sort of chop' is the definition.
(I've seen this before)
'artist fed to shrew' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'fed to' means one lot of letters goes inside another.
'shrew' becomes 'kate' (Katherina or Kate in The Taming of the Shrew).
'ra' put into 'kate' is 'KARATE'.
(Other definitions for karate that I've seen before include "Japanese form of unarmed combat" , "Combative sport" , "A taker (anag)" , "Oriental-style chops" , "SPORT/GAME" .)
