She made sure right rule got a make-over (9)
I believe the answer is:
regulator
'she made sure' is the definition.
I can't judge whether this defines the answer.
'right rule got a make-over' is the wordplay.
'right' becomes 'r' (common abbreviation).
'make' indicates anagramming the letters.
'over' is a charade indicator (letters next to each other) (in a down clue, some letters go over others).
'rule'+'got'+'a'='rulegota'
'rulegota' anagrammed gives 'regulato'.
'r' after 'regulato' is 'REGULATOR'.
Can you help me to learn more?
(Other definitions for regulator that I've seen before include "Governor" , "source of rules?" , "part of the watch" , "Controller" , "Supervisor" .)
