广 (guǎng) as a standalone adjective means 'broad, extensive' and is often used in fixed phrases or before nouns of scope (e.g., 范围广, 知识广). It is more general and concise than the compound forms like 广泛 (wide-ranging), 广大 (vast, numerous), or 广阔 (vast physical space). Unlike 宽 (kuān), which primarily describes physical width and leniency, 广 applies mainly to abstract range and distribution.
