Excessive pride in hideous orange car (9)
I believe the answer is:
arrogance
'excessive pride' is the definition.
'arrogance' can be an answer for 'pride' (arrogance is a kind of pride). I'm not certain of the 'excessive' bit.
'hideous orange car' is the wordplay.
'hideous' indicates anagramming the letters (I've seen this in other clues).
'orange'+'car'='orangecar'
'orangecar' with letters rearranged gives 'ARROGANCE'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for arrogance that I've seen before include "Offensive sense of superiority" , "Wild self-importance" , "Excessive self-importance" , "Conceitedness" , "Hauteur" .)
