Refers to a person's outward demeanor, comportment, or the way they carry themselves. Rare and somewhat formal; in modern Japanese, 態度 or 振る舞い are more common.

Composed of 儀 (ceremony, manners) and 容 (appearance, form). The exact historical derivation is uncertain; the word is a Sino-Japanese compound with a classical feel.
