Radical takeover of the east on battlefield really spoke to one (9)
I believe the answer is:
resonated
'radical takeover of the' is the definition.
I can't judge whether this definition defines the answer.
'east on battlefield really spoke to one' is the wordplay.
I cannot quite understand how this works, but
'east' could be 'e' (abbreviation) and 'e' is located in the answer.
'on' could be 'at' (I've seen this in other clues) and 'at' is located in the answer.
'really' could be 'so' (both can mean 'extremely') and 'so' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for resonated that I've seen before include "Vibrated sympathetically" , "Continued to ring" , "Rung" , "struck a chord" , "Reverberated" .)
