expand
📈 扩 = expand + 展 = unfold; together: expand and unfold outward
扩 (kuò) means to enlarge or widen, and 展 (zhǎn) means to open up or unfold. Combined, 扩展 covers expanding scope, extending reach, or spreading something out — used for territory, business, features, or knowledge.
扩 — hand radical 扌 + 广 (kuàng/guǎng, wide)
扩 is the simplified form of 擴. It is a semantic-phonetic compound: the hand radical 扌 suggests the action of pushing or stretching, while 广 hints at the sound and the idea of wideness. Together they convey 'to extend' or 'to expand'.
