Etymology

副 combines 畐 (a container or vessel) with 刂 (knife). The original idea likely involved splitting or dividing a container, leading to the sense of a secondary or duplicate part. The exact historical development is uncertain.

Meaning mnemonic

A knife 刂 splits a container 畐 into two parts: the main part and its duplicate or assistant. Think of a vice-president who is the secondary copy of the president.

Reading mnemonic

For フク, imagine a vice-assistant wearing a fuku (服, clothing) that is a duplicate of the boss's outfit: fuku -> フク.
