Cargo near wrong side? (9)
I believe the answer is:
arrogance
'side?' is the definition.
(thesaurus)
'cargo near wrong' is the wordplay.
'wrong' is an anagram indicator.
'cargo'+'near'='cargonear'
'cargonear' anagrammed gives 'ARROGANCE'.
(Other definitions for arrogance that I've seen before include "Wild self-importance" , "Excessive self-importance" , "Overbearing attitude of pride and insolence" , "disdain" , "Overweening self-importance" .)
