Clear dispute about Henry’s cricketing blunder (9)
I believe the answer is:
overthrow
'cricketing blunder' is the definition.
I can't tell whether this definition defines the answer.
'clear dispute about henry's' is the wordplay.
'clear' becomes 'overt' (both can mean apparent or obvious).
'dispute' becomes 'row' (row is a kind of dispute).
'about' is a charade indicator (letters next to each other).
'henry' becomes 'H' (symbol for the unit of electrical inductance).
'row' put after 'h' is 'hrow'.
'overt'+'hrow'='OVERTHROW'
Can you help me to learn more?
(Other definitions for overthrow that I've seen before include "destruction" , "Worst" , "Vanquish" , "Subvert" , "Unexpected run" .)
