Wiggling ends, pair did twist (8)
I believe the answer is:
sprained
'did twist' is the definition.
Although both the answer and definition are past participle verbs, I can't see how one could define the other.
'wiggling ends pair' is the wordplay.
'wiggling' indicates anagramming the letters (letters wiggle around).
'ends'+'pair'='endspair'
'endspair' with letters rearranged gives 'SPRAINED'.
Can you help me to learn more?
(Other definitions for sprained that I've seen before include "Ricked" , "Wrenched a ligament, causing pain and swelling" .)
