Meaning & readings

double, twice, times, fold

On’yomi バイ
Nanori べ、ます

Origin

The character 倍 combines a person marker on the left with a sound component on the right. The right side, 咅, is a sound hint that tells you roughly how to pronounce the character, not what it means. The sense of "double" or "multiply" likely comes from the idea of doubling a person's effort or strength — one person becomes two people's worth of work. Over time, the meaning broadened to "double" or "times" in a mathematical sense.
