藟

• Noun: A vine or creeper (specifically a plant that cannot support its own weight).
• Verb: To wind, creep, or trail.

The distinction between the noun (the botanical object) and the verb (the process of winding/spreading) is fluid; usage depends on syntactic position.

Semantic variant: 蔓 (màn). These are largely interchangeable, though 藟 appears more frequently in archaic layers or strictly botanical contexts, while 蔓 became the later standard and is more commonly associated with metaphorical extensions.

The component 曼 carries the sense of "long," "extended," or "lingering"; the grass radical anchors this abstract extension to a plant, emphasizing the process of lengthening and trailing.
