Everyone around him felt uncomfortable with his haughty attitude.
His arrogant and insolent remarks lowered his reputation.
高慢 also means arrogant but can imply a more general pridefulness; 傲岸 specifically suggests a supercilious, overbearing attitude.
Standard kanji spelling.
Irregular kanji usage; 傲 is the correct character.
The kanji 傲 means 'proud' or 'haughty', and 岸 means 'shore' or 'bank', but here it is used in the sense of 'high' or 'elevated', suggesting a lofty and disdainful attitude. The exact historical derivation is uncertain.
