‘草稿纸’ literally means ‘draft paper’ — combining 草 (cǎo, ‘rough’ or ‘preliminary’), 稿 (gǎo, ‘draft’ or ‘manuscript’), and 纸 (zhǐ, ‘paper’). It refers specifically to inexpensive, unlined or lightly lined paper used for jotting down quick notes, calculations, sketches, or early versions of writing before producing a final version. Unlike formal stationery, 草稿纸 is meant to be temporary and disposable, often recycled or reused.

This term is commonly used in school, office, and exam settings — students use it during math tests to work out problems, writers sketch story ideas on it, and professionals scribble meeting notes or brainstorming points. It carries no connotation of quality or permanence; rather, it emphasizes function and practicality. While the word contains 草 (which also means ‘grass’), here it functions purely as a morpheme meaning ‘rough’ or ‘unrefined’, not related to plants.
