Orders in street preceding commotions (12)
I believe the answer is:
instructions
'orders' is the definition.
(I've seen this before)
'in street preceding commotions' is the wordplay.
'street' becomes 'st'.
'preceding' is a charade indicator (letters next to each other).
'commotions' becomes 'ructions' ('ruction' can be a synonym of 'commotion'**).
'in'+'st'+'ructions'='INSTRUCTIONS'
(Other definitions for instructions that I've seen before include "Directions; commands" , "Directions, orders" .)
