Like Richard Burton and Anthony Hopkins (5)
I believe the answer is:
welsh
'like richard burton and anthony hopkins' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for welsh that I've seen before include "Fail to pay debt" , "- Dresser; - rarebit; - harp" , "From a principality" , "Dresser, harp or rabbit" , "Native to, eg, Cardiff" .)
