TV Doctor pulled up on his word to supply tips? (3)
I believe the answer is:
who
'tv doctor' is the definition.
(I've seen this in other clues)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for who that I've seen before include "medical experts" , "Which person?" , "The - - , rock legends" , "Time-travelling Doctor" , "Question of identity" .)
