廴

According to Shuowen Jiezi (説文解字 shuōwén jiězì), the character is a pictograph derived from 彳, stretched out and elongated to represent walking a longer distance (a descriptive character, 지사자).

When used as a radical, it generally conveys meanings related to walking or traveling along a path.

In fact, this character's form became established either because it was mistaken for similar characters like 辵 or 彳 or was deliberately elongated to distinguish it from them.

Ultimately, 廴 does not have a distinct meaning from 彳 or 辵, and most characters containing 廴 have variant forms that substitute 辵 or 彳.
