Etymology

剤 is the modern simplified form of 劑. The older form combines 刀 (knife) with 齊 (even, uniform), suggesting cutting and preparing a uniform mixture, which fits the idea of a measured medicinal dose.

Meaning mnemonic

The left side 斉 suggests something even or uniform, and the right side 刂 is a knife. Imagine a pharmacist using a knife to cut and prepare an even dose of medicine.

Reading mnemonic

For ザイ, picture a pharmacist measuring out a dose of medicine and saying 'This is the exact size (サイズ) you need.' The 'size' sound cues ザイ.
