invade
🚪🪖 入 (enter) + 侵 (encroach) = enter-by-force = invade
入 rù means enter or go in; 侵 qīn means to encroach or trespass on. Together they describe forces entering territory that is not theirs. Sound cue: rùqīn ends like the kin you do not want crossing your border.
入 — single pictograph, two slanting strokes
入 is a pictograph showing an arrowhead or pointed entrance, with two strokes converging downward to suggest something going inward. The original sense was 'to enter,' and it still carries that meaning today. It contrasts visually with 人 (person), where the strokes cross differently at the top.
