广泛 (guǎng fàn) is an adjective meaning 'extensive' or 'widespread', describing something that covers a large scope, area, or range—whether in space, time, quantity, or social reach. The first character 广 (guǎng) means 'broad' or 'wide', evoking openness and expansiveness; the second character 泛 (fàn) means 'to spread' or 'to be general', suggesting diffusion or broad applicability. Together, they emphasize both breadth and dispersion—like information spreading across many regions or a practice adopted by many people.

This word commonly modifies nouns such as 影响 (influence), 应用 (application), 参与 (participation), or 讨论 (discussion). It often appears in formal or written contexts—news reports, academic writing, or official statements—but is also used naturally in speech when describing inclusive or far-reaching phenomena. It does not describe physical size alone (e.g., not for 'a wide river'), but rather abstract or collective extent: widespread support, extensive research, broad participation.
