Etymology

酢 combines 酉 (sake jar, indicating fermentation) with 乍, which likely contributes the sound. The character originally referred to sour fermented liquids, hence vinegar.

Meaning mnemonic

The sake jar 酉 on the left suggests fermentation, and the right side 乍 looks like a sharp, jagged tool. Imagine a jar of fermented liquid so sour it feels sharp on the tongue—that's vinegar.

Reading mnemonic

For サク, imagine a sack of sour vinegar: sack -> サク, and the sharp smell hits you when you open it.
