The word 范围 is formed through the logical combination of two meaningful characters: 范, which carries the core idea of a model, pattern, or boundary (like the edge of a mold); and 围, which means to encircle, surround, or enclose. Conceptually, they merge to depict the idea of an area that is encircled and defined by its boundaries, literally, an "encircled model", which naturally extends to the abstract meaning of "scope", "range", or "limits". It is a classical example of a compound where the two components reinforce and specify a single, unified concept.
