Grand mechanical procedure's what Parisian finds bizarre (9)
I believe the answer is:
grotesque
'bizarre' is the definition.
(I've seen this before)
'grand mechanical procedure's what parisian' is the wordplay.
'grand' becomes 'g' (G is short for grand as in a thousand).
'mechanical procedure's' becomes 'rotes' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'what parisian' becomes 'que' ('what' in French).
'g'+'rotes'+'que'='GROTESQUE'
'finds' is the link.
Can you help me to learn more?
(Other definitions for grotesque that I've seen before include "Fantastically hideous" , "Outlandish" , "Weird" , "Bizarre and disfigured - preposterous" , "Freakish" .)
