U+53B4 "厴" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

厴

U+53B4 "厴" CJK Unified Ideograph-# is a Han character primarily used in traditional Chinese and Japanese contexts, where it functions as a variant or component in compounds related to shellfish, covering, or a clasp, often appearing in words like "厴蟹" to denote the operculum or trap door of certain mollusks. In Japanese, it is known as the kanji for the lid or door of a shell, and it carries the radical for "cliff" or "factory" (厂) with a phonetic component, reflecting its historical usage in descriptions of natural or constructed enclosures. Despite its infrequent appearance in modern simplified Chinese, this character remains a recognized element in classical texts and specialized terminology, preserving a nuanced link to biological and architectural concepts across East Asian languages.
