It is composed of the radical 门 (gate, door) which encloses the phonetic component 或 (huò), and is traditionally used to refer to the wooden or stone barrier at the bottom of a doorway, as well as metaphorically to denote a boundary, limit, or a domain of activity, such as in the common term 视阈 (shìyù) meaning "visual field" or "horizon." In simplified Chinese, it retains the same form and meaning, and it is encoded in the Unicode standard under the CJK Unified Ideographs block, representing a well-attested character in written Chinese.
