📐 范 = pattern/mold + 围 = surround → the scope something covers
范 originally meant a casting mold (a fixed pattern), and 围 means to enclose or surround. Together they mark the bounded area or extent that a topic, rule, or measurement reaches.
围 — enclosure 囗 + wéi 韦 (phonetic)
围 is a semantic-phonetic compound. The outer 囗 ('enclosure') gives the meaning of surrounding or enclosing, while 韦 supplies the sound. The traditional form 圍 shows the same structure; 围 is its simplified version. Core sense: to surround, encircle, or enclose.
