🔲 囗 (enclosure) + 韦 (leather strap) — leather wrapped around a boundary
围 means to surround or encircle. The outer 囗 is the enclosure radical (a boundary), and 韦 (wéi, leather/tanned hide) gives the sound. Together: a leather strap encircling something — to surround.
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.
