石
いし · ishi · JLPT N4 · noun
rock
🪨 ishi sounds like itchy: an itchy STONE stuck in your shoe
Say ishi fast and it lands close to itchy. A stone in your shoe is the classic itch you cannot ignore. The kanji 石 began as a cliff with a rock (口) fallen beneath it, so the little box at the bottom is the stone itself.
