Regime controller cut out missing painter (6)
I believe the answer is:
titian
'painter' is the definition.
(Titian is an example)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for titian that I've seen before include "Venetian fifteenth-sixteenth century painter" , "The painter Tiziano Vecellio" , "Italian Old Master and colour" , "Painter of 16th century" , "Venetian painter - shade of red" .)
