奠定

establish
🏛️ DIAN-DING sounds like laying a DEN's DINGs — establishing a foundation
奠 means to settle or lay a foundation (used in rituals placing offerings on the ground). 定 means fixed or settled. Together: to establish something firmly, like laying the groundwork for a project or nation.
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.'
