案
あん · an · JLPT N3 · noun
plan
📋 安 (an, calm) over 木 (wood): a quiet wooden desk where plans get drafted
案 first meant a wooden desk or tray, and 木 at the bottom marks it as wood. The top part, 安, gives the sound an. Proposals were written at the desk, so the word came to mean plan or proposal, as in 提案 (ていあん, proposal).
