🌐 广 = wide + 泛 = float/overflow; wide-spreading reach
广 means wide or broad; 泛 originally meant to float on water, extended to overflow or spread widely. Together they describe something that spreads broadly — extensive, wide-ranging coverage.
广 — shelter/roof radical 广 (yǎn)
广 originally depicted a building leaning against a cliff or hillside — a roof or shelter open on one side. It serves as the 'shelter' radical (yǎn) in many characters related to buildings (店, 庭, 库). In simplified Chinese, 广 was also adopted as the simplified form of 廣 ('wide, broad').
