From Cardiff? (5)
I believe the answer is:
welsh
'from cardiff?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for welsh that I've seen before include "Nationality of Dai or Ivor" , "Cambrian" , "Native to, eg, Cardiff" , "Leave without paying" , "Owain Glyndwr?" .)
