Meaning & readings

measurement, tenth of a shaku, a little, small

On’yomi スン
Nanori す、みき

Origin

This character appears to be a simple pictograph showing a hand with a marked segment on the forearm or wrist. The mark represents a small unit of measurement — roughly the distance from wrist to elbow, or a similar body-based measure used in ancient times. Because this measurement is naturally short compared to larger body parts, the character came to mean "small" or "a little," and it became the standard unit called a "sun" in the traditional Japanese measurement system.
