Etymology

確 combines 石 (stone) with 隺, which likely contributes the sound and the idea of something high or solid. Together they suggest the hardness and certainty of stone.

Meaning mnemonic

Stone (石) is hard and solid. The right side (隺) looks like a tall, firm structure. Imagine a stone pillar that is unshakable—this is the essence of 確: firm, certain, and confirmed.

Reading mnemonic

For カク, picture a solid rock that makes a sharp 'kak' sound when struck: kak -> カク, confirming its hardness.
