製法
せいほう · seihou · JLPT N1 · noun
method
🏭 製 = make + 法 = method, so 製法 = make-method = manufacturing method, or recipe
製 also appears in 製品 (product) and 製造 (manufacture). 法 also appears in 方法 (method) and 文法 (grammar). Together they mean a set procedure for making something.
法 — water 氵 + go 去
Originally written 灋, combining the water radical 氵 (suggesting a level standard, like water finding its level), the mythical beast 廌 (which judged guilt), and 去 (to remove or banish). The 廌 was later dropped, leaving 法. The core meaning evolved from 'law' or 'standard' to also include 'method' and 'way of doing'.
