設計
せっけい · sekkei · JLPT N3 · noun
design
📐 設計 = set up + calculate: you set things up after calculating them
設 means to set up or establish (as in 設置, installation), and 計 means to measure or plan (as in 計画, plan). Calculating first and then setting up is what a design is. The sound helps too: sekkei is close to sketch.
