Some bride’s potentially a tyrant (6)
I believe the answer is:
despot
'tyrant' is the definition.
(synonyms)
'some bride's potentially a' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'DESPOT' is hidden in the letters of 'brides potentially a'.
(Other definitions for despot that I've seen before include "Posted (anag)" , "Tyrant, dictator" , "Person with more than enough power" , "who treats others badly?" , "monster?" .)
