推广
tuīguǎng · HSK 3
extend
📣 推 = push + 广 = wide; pushing something out wide = popularize
推 (tuī) means push/promote and 广 (guǎng) means wide/broad. Together: push something wide — to spread, extend, or popularize. Common in marketing contexts like 推广活动 (promotional campaign).
推 — hand radical 扌 + 隹 (short-tailed bird)
A semantic-phonetic compound: the hand radical 扌 gives the meaning 'to push' or act with the hand, while 隹 supplies the sound (originally close to 'tui'). The core sense has stayed remarkably stable, expanding from physical pushing to figurative uses like 'recommend' or 'infer'.
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').
