Send mad Commie back, row initially avoided (7)
I believe the answer is:
derange
'send mad' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for derange that I've seen before include "Make mad" , "Put into confusion" , "Drive mad" , "Throw into disorder" , "Craze" .)
