Tear apart Mockingbird’s meme (9)
I believe the answer is:
dismember
'tear apart' is the definition.
(thesaurus)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for dismember that I've seen before include "cut to pieces" , "Separate limbs from the body" , "Dissect" , "Tear limb from limb" , "Divide up (organisation)" .)
