Brought into existence the extremes of the Marquis de Sade (4)
I believe the answer is:
made
'brought' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'existence the extremes of the marquis de sade' is the wordplay.
'existence' becomes 'ma' (I can't justify this - if you can you should believe this answer much more).
'the extremes of' says to hollow out the word (remove centre letters).
'the marquis de sade' becomes 'desade' ('de Sade' can be a synonym of 'marquis de sade').
'desade' with its centre removed is 'de'.
'ma'+'de'='MADE'
'into' acts as a link.
Can you help me to learn more?
(Other definitions for made that I've seen before include "Performed" , "One renovating (painting)" , "Created" , "Built" , "Manufactured" .)
