Cricket matches controlled by entitled son’s rule? (9)
I believe the answer is:
principle
'rule?' is the definition.
(principle is a kind of rule)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for principle that I've seen before include "Morally correct behaviour" , "Set of rules" , "honour" , "Rule of personal conduct" , "Precept, rule" .)
