Doctor returned after a cricket team accepted truth (5)
I believe the answer is:
axiom
'accepted truth' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for axiom that I've seen before include "rule" , "Proposition assumed to be self-evident" , "Truth assumed to be self-evident" , "Dictum" , "Basic proposition" .)
