Driven crazy by the English (4)
I believe the answer is:
made
'driven' is the definition.
Both the answer and definition are adjectives. Maybe you can see an association between them that I can't see?
'crazy by the english' is the wordplay.
'crazy' becomes 'mad' (synonyms).
'by' means one lot of letters go next to another.
'the english' becomes 'e' (abbreviation).
'mad'+'e'='MADE'
Can you help me to learn more?
(Other definitions for made that I've seen before include "Manufactured" , "Built" , "Created" , "Produced" , "One renovating (painting)" .)
