小 — Kanji Meaning, Readings & Example Words (JLPT N5)

N5deep-diveUpdated 2026-06-23

What it means

At its heart, 小 is about being small or little — the natural opposite of 大 ("big"). You'll meet it in three roles: as the standalone adjective 小さい ("small"), as the on'yomi building block ショウ inside compounds (小学校 "elementary school," 小説 "novel"), and as a friendly prefix こ- / お- that shrinks the word it attaches to (小鳥 "little bird," 小川 "small stream"). Whenever you spot 小 in a word, you can bet it carries some sense of "small" — a quick head start on the meaning.

Readings

TypeReadingUsed in
kun'yomiちい.さい小さい (small)
kun'yomi (prefix)こ-小鳥 (ことり, little bird), 小声 (こごえ, soft voice)
kun'yomi (prefix)お-小川 (おがわ, stream, brook)
on'yomiショウ小学校 (elementary school), 小学生 (elementary student), 小説 (novel)

Here's a rule of thumb that works for most kanji: the kun'yomi (ちい.さい) shows up when the kanji stands more or less alone with a hiragana ending, while the on'yomi (ショウ) appears inside two-kanji-and-up compounds. So 小さい uses ちい.さい, but 小学校 uses ショウ. The tricky extras here are the prefixes こ- (小鳥) and お- (小川) — when 小 sits in front of a word to mean "little," it often takes one of these instead.

Stroke order & radical

Because 小 is so simple, it's a great early win: three strokes, one clear meaning, and a shape that's hard to forget.

小学生 しょうがくせいelementary school studentN5
小説 しょうせつnovelN5
小鳥 ことりsmall birdN5
小川 おがわstream, brookN5

Notice the reading split in action: the lone adjective 小さい takes ちい.さい, the compounds (小学校, 小学生, 小説) flip to ショウ, and the "little ___" words use the prefixes — こ- in 小鳥 and お- in 小川.

Example sentences

ヤッタンは小さい家に住んでいます。

ヤッタンは ちいさい いえに すんでいます。

小さい — the kun'yomi ちい.さい reading (the い-adjective 'small').

モチは小学生のとき、小説を書きました。

モチは しょうがくせいの とき、しょうせつを かきました。

When Mochi was an elementary school student, she wrote a novel.

Two on'yomi compounds: 小学生 (ショウ) and 小説 (ショウ).

弟は小川のそばで小鳥を見ました。

おとうとは おがわの そばで ことりを みました。

My little brother saw a small bird by the stream.

Both prefix readings together: 小川 (お-) and 小鳥 (こ-).

Frequently asked questions

How do you read 小 in 小さい vs 小学校?

In 小さい it's the kun'yomi ちい (小さい = ちいさい, 'small'). In 小学校 it's the on'yomi ショウ (小学校 = しょうがっこう, 'elementary school'). As a rule, compounds take the on'yomi.

How many strokes does 小 have?

小 has just 3 strokes: the center vertical hook first, then the left dot, then the right dot. It's also the 'small' radical.

Why is 小 read こ in 小鳥 but お in 小川?

Both こ- and お- are kun'yomi prefixes meaning 'little / small,' and which one a word uses is fixed by custom. 小鳥 (ことり, 'little bird') takes こ-, while 小川 (おがわ, 'stream') takes お-. These are worth memorizing word by word.

What's the opposite of 小?

The opposite is 大 (おお.きい / ダイ), meaning 'big, large.' Learning 小 and 大 together makes both easier to remember.
