'wound' is the definition.
The answer and definition can be both to do with motion as well as being past participle verbs.
Maybe you can see a link between them that I don't see?

'a red pill's designed' is the wordplay.
'designed' indicates anagramming the letters (designed with the letters).
'a'+'red'+'pills'='aredpills'
'aredpills' with letters rearranged gives 'SPIRALLED'.

'for' acts as a link.

Can you help me to learn more?
