碗
わん · wan · JLPT N3 · noun
bowl
🍚🥣 Wan sounds like one: one bowl of rice, please
The kanji is 石 (stone) + 宛, which gives the sound. Early bowls were made of stone or ceramic. In Chinese, the same character is read wǎn, so it sounds almost the same in both languages.
碗 — stone radical 石 + 宛 (wǎn, phonetic)
碗 is a semantic-phonetic compound. The 石 radical originally indicated stone or hard material, reflecting that early bowls were made of stone or pottery; later it came to cover ceramic and porcelain bowls too. The component 宛 supplies the pronunciation wǎn.
