Meaning

倍 centers on multiplication: making something double, twice as much, or several times larger. The idea of 'fold' extends naturally from that same sense of repeated increase.

Etymology

倍 combines 亻 (person) with 咅, which likely contributes the sound and carries a sense of doubling or increasing. The exact historical development of 咅 is uncertain.

Meaning mnemonic

A person 亻 standing beside 咅, which looks like a mouth 口 over a stand 立, as if someone is speaking twice as loud or repeating themselves: that doubling is the core of 倍.

Reading mnemonic

For バイ, imagine buying one item and getting double: buy -> バイ, and the person 亻 gets twice as much.
