落着く
おちつく · ochitsuku · JLPT N2 · verb-godan
to calm down
🍂 落 (fall) + 着 (arrive, reach): a thing falls and lands to rest, so you settle down
A falling leaf drops and then comes to rest on the ground. Ochitsuku works the same way: agitation drops away and you land in a calm state.
落 — grass radical 艹 + 洛 (water 氵 + 各)
Originally written with the grass radical 艹 over 洛, depicting leaves falling from plants. 洛 serves as the phonetic component (giving the luò sound) while 艹 supplies the meaning of vegetation. The sense extended from 'leaves falling' to the general meaning of falling, dropping, or settling down.
着 — sheep 羊 (top) + eye 目 (bottom)
着 originated as a variant of 著, which depicted plants emerging visibly above ground (grass radical 艹 over 者). Over time 着 split off to carry meanings like 'attach,' 'wear,' or a verb suffix marking ongoing action (zhe), while 著 kept senses like 'manifest' or 'author.'
