Katakana Letter Mo

モ represents the Japanese sound “mo”; it has no fixed meaning alone. In a word, the surrounding sounds and characters give it meaning. If someone sends only モ, the character by itself does not tell you what they intend.

Where did モ come from?

Katakana grew from shortened characters used to annotate Chinese texts. In the early ninth century, Buddhist scholars used these marks to add Japanese readings between lines of Chinese writing. The shorter forms saved space and effort, and became more standardized by the twelfth century. These dates describe katakana’s development, not the first appearance of モ.

モ took its shape from the final three strokes of 毛. Hiragana も developed from a cursive form of 毛. Both kana belong to the older practice of using Chinese-derived characters, called kanji in Japanese, for their sounds; this practice is known as man’yōgana. 毛 and 母 were among the characters used for the “mo” sound.

Why use katakana in Japanese?

Katakana marks a writing choice, not a different sound. Japanese uses it for loanwords and foreign names, technical terms, plant and animal names, and sound-imitating words. It can also emphasize a native Japanese word, so katakana does not automatically mean “foreign.”

Katakana grew beyond its beginnings as a reading aid and became part of academic and practical writing. It appeared in official documents in prewar Japan, before the Second World War.
