The Child: 子 – A Swaddled Baby in Every Kanji

The Shape of 子

Imagine a baby, tightly wrapped in a blanket, only its head peeking out. That’s the picture behind the kanji 子 (こ, child). In its earliest form, it showed a large head with tiny arms, swaddled and helpless. Over thousands of years, the picture got tidied into the simple strokes we see today: a horizontal line for the head, a vertical line for the body, and a little hook for the arm. Once you see it, you can’t unsee it.

子 is not just a word; it’s also a radical. It appears in many kanji, often carrying the idea of a child or learning. Let’s look at two common ones.

好: A Mother and Her Child

The kanji 好 (この, to like; す, to like) is made of two parts: 女 (woman) on the left and 子 on the right. The story goes that a mother holding her child is something to like—a picture of affection. So 好 means “to like” or “to be fond of.”

• 好き (すき, liked; to like) – as in 私は猫が好きです (わたし は ねこ が すき です, I like cats).
• 好きな (すきな, favorite) – 好きな本 (すきな ほん, favorite book).

When you see 好, think of a mother and child—a bond that feels good.

学: A Child Under a Roof

The kanji 学 (まな, to study; がく, learning) is a bit more abstract. Its top part is a simplified form of 爻, which originally showed two hands holding sticks or counting rods—an ancient tool for learning. Below that is 子, the child. So 学 literally depicts a child learning under a roof. It’s a picture of education.

• 学生 (がくせい, student) – 私は学生です (わたし は がくせい です, I am a student).
• 学校 (がっこう, school) – 学校に行きます (がっこう に いきます, I go to school).
• 勉強 (べんきょう, study) – 勉強します (べんきょう します, I study).

Other Children in Kanji

子 also appears in words like 子供 (こども, child) and 椅子 (いす, chair)—though the 子 in 椅子 is just a phonetic, not a meaning. And in names, 子 is a common ending for female names, like 美子 (よしこ) or 花子 (はなこ), meaning “child” in a poetic sense.

A Bridge to Yesterday and Tomorrow

Yesterday we saw how 門 (door) gave us 聞 (to hear) and 問 (to ask). Today, 子 gives us 好 and 学. Both kanji show how a simple picture can carry meaning across centuries. But there’s another side to this story: the woman in 女. In 好, she holds the child. In 始 (はじ, to begin), she is the first stroke. What does her kneeling pose tell us about ancient society? And how does she shape the kanji we use every day?

Tomorrow, we’ll honor the woman in 女 and see her in 好 and 始. You might never look at these characters the same way again.
