Edward tours the kingdom getting drastically treated! (5)
I believe the answer is:
nuked
'drastically treated' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Maybe there's a link between them I don't understand?
'edward tours the kingdom' is the wordplay.
'edward' becomes 'Ned'.
'tours' is an insertion indicator (to tour can mean to go around).
'the kingdom' becomes 'UK' (UK is an example).
'ned' going around 'uk' is 'NUKED'.
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for nuked that I've seen before include "Used bombs" , "zapped into oblivion?" .)
