定 — roof 宀 + 正 (correct/upright, phonetic)
Originally written with 宀 (roof) over 正 (upright/correct), suggesting a household settled and orderly under its roof. Over time 正 simplified to 㐬-like form at the bottom, and the meaning shifted from 'settled home' to the broader senses of 'fix, stable, decide.'

setting
⚙️ 設定 = set up (設) + fix/decide (定): setting things up and fixing them in place
設 means to establish or set up, as in 設計 (design) and 設備 (equipment). 定 means to fix or decide, as in 決定 (decision) and 予定 (plan). Handy sound hook: settei starts just like the English word set, so settei = settings.
