5-Second Memory Summary: How to Never Mix Up 石 & 右 & 研 Again
For 石 vs. 右: a flat overhanging cliff roof (no poke-through at the top) drops a 石 (Stone — ishi), and putting 石 on the left of 开 gives 研 (Polish a stone — 研究 kenkyū 'research')! If the stroke pokes up through the top bar, it is your 右 (Right — migi) hand!
