Registered pain from Dr White's manipulation (7)
I believe the answer is:
writhed
'registered pain' is the definition.
Although both the answer and definition are past participle verbs, I don't understand how one could define the other.
'dr white's manipulation' is the wordplay.
'manipulation' indicates anagramming the letters (I've seen this in other clues).
'dr'+'white'='drwhite'
'drwhite' with letters rearranged gives 'WRITHED'.
'from' acts as a link.
Can you help me to learn more?
(Another definition for writhed that I've seen is " Squirmed. twisted".)
