Form of ban omits cars when on the move (9)
I believe the answer is:
ostracism
'form of ban' is the definition.
'ostracism' can be an answer for 'ban' (thesaurus). I am unsure of the 'form of' bit.
'omits cars when on the move' is the wordplay.
'omits cars' can be anagrammed to 'OSTRACISM'.
But, I'm unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for ostracism that I've seen before include "isolation" , "being sent to Coventry" , "transferring to Coventry?" , "Banishment" , "cold shoulder" .)
