Villain shows vigour heading north in Parisian street (5)
I believe the answer is:
'villain' is the definition.
(I know this)
'vigour heading north in parisian street' is the wordplay.
'vigour' becomes 'go' (go can mean energy or vigour).
'heading north' shows that the letters should be reversed in order.
'in' indicates putting letters inside.
'parisian street' becomes 'rue' ('street' in French).
'go' written backwards gives 'og'.
'og' going inside 'rue' is 'ROGUE'.
'shows' acts as a link.
(Other definitions for rogue that I've seen before include "one behaving atypically" , "Baddy" , "Chap in gallery" , "Scoundrel, knave" , "Diseased plant" .)
