粗略 (cū lüè) is an adjective meaning 'rough', 'approximate', or 'cursory'. It combines 粗 (cū), which means 'coarse' or 'rough', and 略 (lüè), meaning 'brief' or 'to omit'. Together, they convey the idea of something done without fine detail—skimming the surface rather than examining thoroughly. The word often describes estimates, summaries, inspections, or preliminary understandings.

It's commonly used in academic, professional, and everyday contexts—for example, giving a rough estimate of time or cost, doing a quick review of material before a meeting, or describing an initial assessment that lacks precision. While it carries no negative connotation by itself, context may imply insufficiency if thoroughness is expected. It’s more formal than colloquial alternatives like 大概 (dàgài) but less technical than 精确的 (jīngquè de).
