Supercilious types lose row about throughway (7)
I believe the answer is:
haughty
'supercilious' is the definition.
(I know that supercilious can be written as haughty)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for haughty that I've seen before include "Supercilious" , "contemptuous" , "Proud - self-satisfied" , "Imperious, arrogant" , "Proud, arrogant" .)
