Spin or twist in jail (6)
I believe the answer is:
prison
'jail' is the definition.
(I know that jail can be written as prison)
'spin or twist' is the wordplay.
'twist' indicates an anagram (a twisted or distorted version of the letters).
'spin'+'or'='spinor'
'spinor' anagrammed gives 'PRISON'.
'in' acts as a link.
(Other definitions for prison that I've seen before include "Wormwood Scrubs, for example" , "Cooler" , "Place of confinement" , "Slammer" , "Eg, Wormwood Scrubs" .)
