Spanish Inquisitor removed parents using twisted force (6)
I believe the answer is:
torque
'force' is the definition.
(force in physics)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for torque that I've seen before include "measure of twist" , "Force causing rotation in mechanism" , "Quoter (anag.)" , "Turning force" , "Rotating forces" .)
