Obtains by force, being a twister maybe (6)
I believe the answer is:
wrests
'obtains' is the definition.
Although both the answer and definition are verbs in their -s form, I cannot understand how they can define each other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for wrests that I've seen before include "Seizes forcibly" , "Takes" , "Obtain by seizing forcibly or violently" .)
