L17. Daily Japanese Kanji — Lesson 17: 力
Days 11-20
R-report
[Day 17] 力 - Power / Strength
The character 力 originally depicts a bent arm or muscle and is used to express physical strength, force, and power more generally. You will see it in words about physical ability (e.g., 力持ち), effort or capacity (努力, 効力), and technical power (電力). Readings: On'yomi: リョク (ryoku), リキ (riki) — used in compounds like 電力 (でんりょく, denryoku) and 力学 (りきがく, rikigaku). Kun'yomi: ちから (chikara) — the common native word for "power/strength," used on its own and in phrases (力を入れる). Mnemonic tip: imagine the kanji as a bent arm ready to push — that helps link the shape to strength.
