容

Its compound supplies the intended sense. 容器 means “container,” 容認 means “acceptance” or “permission,” and 容貌 means “appearance.” In Mandarin, its pinyin spelling (Latin letters for Mandarin sounds) is róng, said with a rising tone and a soft, curled-back initial r. Japanese compounds usually read it よう (yō, with a long o); the verb 容れる can use いれる (ireru, “to contain” or “admit”).

How old is 容?

Its forms appear on Western Zhou bronzes. Early Chinese inscriptions use it for holding or containing. By the Warring States, 容 also wrote a word for bearing or appearance that had earlier been written 頌. 㝐 is a recorded older variant.
