The House Roof Radical (宀 — Ukanmuri): 安 (Cheap/Safe), 宿 (Inn/Homework 宿題), 宅 (Home), 実 (Truth) & 家

Whenever you see the 3-stroke roof with a top chimney tick (宀 — ukanmuri), imagine looking inside a traditional Japanese home. What is under that roof tells you the entire meaning of the kanji!

Look at how logical the 宀 (House Roof) family is: put 女 (Woman) safely indoors under a roof and you get 安 (Peaceful / Safe / Inexpensive — 安い yasui, 安心 anshin). Put a Person (亻) + 100 (百) under a roof and you get 宿 (Inn / Lodging — and take-home assignments: 宿題 shukudai 'homework'!).

Quick Comparison: 安 (Relax) vs. 宿 (Lodge) vs. 宅 (House) vs. 実 (Truth)
