be haughty, proud, arrogant
憍 centers on an inflated sense of self: being haughty, proud, or arrogant. The given meanings all describe a person who looks down on others.
憍 combines the heart radical 忄 with the phonetic component 喬, which likely contributes the sound and may carry a sense of height or loftiness, fitting the idea of arrogance.
The heart radical 忄 beside 喬 (which can suggest tallness) paints a picture of a heart that is puffed up and looking down on others—a proud, haughty attitude.
For キョウ, imagine a proud person in Kyoto (京都, きょうと) looking down on everyone: Kyoto -> キョウ, and their heart is full of arrogance.
