Word origin

The character 凸 (tū, "raised") comes from an ancient pictograph of a section jutting above its surroundings, so its written form preserves the idea of a protrusion.

Usage tips

  • In everyday conversation, speakers often use 凸起 (tūqǐ, "rise up") or 凸出来 (tū chūlái, "stick out") instead of the shorter form alone, especially when describing a road or other surface.
