Lesson 4: 心 (Heart / Mind)

Radicals in 心

The kanji (kokoro, meaning "heart" or "mind") is a simple yet profound character. It stands alone as its own radical, Radical 61, and its shape evokes the image of a heart or the core of something essential. Unlike more complex kanji, 心 has no additional components, but its form is thought to resemble the organ it represents—an ancient depiction of the heart with its curved lines.

  • 心 (Heart Radical): Radical 61, meaning "heart" or "mind," symbolizes emotions, thoughts, and the inner self. Its three strokes curve inward, suggesting something central and alive.

Visually, 心’s elegant simplicity reflects its meaning: the heart or mind as the root of human experience. Fun fact: It appears in countless kanji related to emotions and mental states, acting as a foundation for words like "love" (愛) and "think" (思).
