着实

truly
🪨 着 (apply) + 实 (solid/real) = applied solidly to reality, i.e. truly, really
着 carries the sense of attaching or applying, and 实 means solid or real. Pressed together they mean something is solidly, really so, hence truly or indeed; the same firmness extends to severely or harshly.
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.'
