高大
gāodà · HSK 5
tall and big
🏢 高 = tall + 大 = big; literally tall-and-big
A straightforward compound: 高 (gāo, tall/high) plus 大 (dà, big/large). Stacking the two intensifies the size — used for towering buildings, imposing people, or anything physically grand.
高 — pictograph of a tall building/tower
高 is a pictograph of a tall structure, likely a watchtower or multi-story gate, with a roof on top, an upper chamber, and a base below. From this concrete image of height it extended to the general meanings 'tall,' 'high,' and figuratively 'lofty' or 'noble.'
大 — pictograph of a person with arms outstretched
大 is a pictograph showing a person standing with arms and legs spread wide. The outstretched arms suggest 'big' or 'great', extending from the literal image of a large stance to abstract meanings like important or grand. It is one of the oldest characters, found on oracle bones.
