碗
wǎn · HSK 2
bowl
🥣 碗 = 宀 (roof/cover) + 宛 (wǎn, curved) — a curved container; 宛 also gives the sound
The 宀-like top and 宛 phonetic combine: 宛 supplies both the wǎn reading and the sense of 'curved/bent'. Pairs with 一碗饭 (a bowl of rice) as a measure word for bowl-shaped servings.
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.
