凍
U+51CD "凍" CJK Unified Ideograph-# is a Chinese character meaning "to freeze" or "frozen," commonly used in East Asian languages such as Chinese, Japanese, and Korean. Its visual composition combines the ice radical 冫 on the left with the phonetic component 東 on the right, reflecting both its semantic association with cold and its pronunciation in historical Chinese. In modern usage, it appears in words like 冷凍 (cold storage) and 凍結 (freezing), and it is encoded in the CJK Unified Ideographs block to support the representation of shared Chinese character heritage across digital systems.
