Meaning
Today, we'll explore the versatile kanji 号. This character holds several core meanings, primarily centered around number, sign, signal, call, name, and even the issue of a publication. Essentially, it helps us identify, designate, or communicate something.
The origin of 号 is quite compelling; it's said to stem from the image of a tiger's roar. The top part (which visually resembles 丂, but is a simplification of 虎 'tiger') combined with the bottom 口 (kuchi), meaning 'mouth,' originally depicted a tiger letting out a loud cry. This powerful 'call' or 'shout' then expanded in meaning to 'signal' or 'designation.'
Over time, 号 evolved to represent a 'number' or an 'issue' (like a magazine issue), indicating a specific item in a series. It truly is a fascinating journey from a primal roar to a precise label.
You can see how the visual shape of 号 beautifully connects to its initial meaning: a mouth (口) making a distinctive sound (represented by the upper part, derived from 'tiger'). This sound transforms into a signal, a call, and ultimately, a means to identify or number things. It's a great example of how abstract concepts can emerge from very concrete imagery.
With just 5 strokes, 号 is straightforward to write. Japanese children learn this kanji in the 3rd grade of elementary school, so you'll encounter it frequently in daily life, from street signs to magazine covers!
Readings
On'yomi (音読み) — Chinese-derived readings
The 号 kanji primarily has one On'yomi reading: ゴウ (GŌ). This is the most common way you'll see 号 used in compound words, which simplifies your learning. This reading is highly adaptable and applies to nearly all its core meanings.
- 番号 (bangō) — This means "number," like a phone number (電話番号) or a sequence number, such as your ticket number (整理番号).
- 記号 (kigō) — Meaning "symbol" or "mark." Think of mathematical symbols (+, -) or punctuation marks (?, !).
- 信号 (shingō) — This refers to a "signal," most commonly traffic lights! You'll hear this one often when talking about driving or crossing the street, like in 信号を待つ (shingō o matsu – wait for the traffic light).
- 月号 (getsugō) — This means "issue (of a magazine)" or "monthly issue." For instance, the July issue would be 7月号.
- 号令 (gōrei) — Meaning "command" or "order," often used in military or organized group settings, such as "Attention!" (気をつけ!) given by a drill sergeant.
Kun'yomi (訓読み) — Native Japanese readings
Interestingly, the kanji 号 does not have a commonly used or widely recognized native Japanese Kun'yomi reading when it appears alone. While its etymological roots connect to "calling" or "shouting," these concepts are typically expressed with other kanji or native Japanese words. For example, you would use 呼ぶ (yobu - to call) or 叫ぶ (sakebu - to shout).
Therefore, when you encounter 号, you should almost always expect its On'yomi reading of ゴウ in compounds. This simplifies learning, as you don't need to worry about multiple readings for this character in most everyday contexts. Its versatility truly shines when combined with other kanji to form precise and common terms.

Memory Tip
To help remember 号, we'll revisit its fascinating origin! Picture a powerful tiger (虎, simplified to the upper part of 号) letting out a mighty roar from its mouth (口). This isn't just any sound; it's a distinct call or a signal. Over time, that signal evolves into a way to identify things—like a number in a series, a special sign on a map, or even the issue number of your favorite magazine. So, a useful mnemonic is: A tiger's ROAR (号) acts as a SIGNAL that identifies its TERRITORY (NUMBER/ISSUE). The top part (丂) represents the 'tiger's head,' and the bottom (口) is the 'mouth.' A roaring mouth giving a number or call!
