阜

When the 阝 radical is placed on the left side, it is called the left 阜 radical (⻖, 좌부변, 左阜 边) and originates from the ancient form of 阜 (hill, mound).

When placed on the right side, it is called the right 邑 radical (⻏, 우부방, 右阜 傍) and originates from the ancient form of 邑 (town, village).

The left 阝 (⻖) is mainly used in characters related to geography, such as hills, mounds, or ridges.

The right 阝 (⻏) is mainly used in characters related to place names or settlements (towns, villages).

Notably, the character 阜 itself is not used as a radical by itself in any Chinese character; only its left or right abbreviated forms appear as radicals.

There is also a variant form (informal character) 峊.
