usage
Mostly seen in the literary phrase 一望无垠 ('a boundless expanse as far as the eye can see'), used for deserts, plains, oceans and skies — anything that seems to have no edge.
Earth radical on the left, 土. It anchors the meaning in land and ground — the edge or limit of a stretch of terrain. Same family as 地 ground, 境 border, 坡 slope.
