Lesson 16: 月 (Moon)

Radicals in 月

The kanji (tsuki, meaning "moon") is a simple yet evocative character that stands alone as its own radical, Radical 74. Its shape is a stylized depiction of the crescent moon or the lunar form.

  • 月 (Moon Radical): Radical 74, the entire character, mimics the moon’s curved outline, with two vertical strokes and connecting lines suggesting its glowing arc in the sky.

Visually, 月’s elegant, curved design captures the moon’s serene presence, reflecting its role as a symbol of beauty, time, and mystery in Japanese culture. Fun fact: Beyond meaning "moon," it also represents "month" due to the lunar calendar’s historical influence, and it appears as a radical in kanji related to the body or time, like 胸 (chest) and 期 (period).
