Evolve contract to dispel resistance (5)
I believe the answer is:
educe
'evolve' is the definition.
(synonyms)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for educe that I've seen before include "Extract" , "Infer" , "Draw out, elicit" , "Bring out (something)" , "Bring out, develop" .)
