U+5451 "呑" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

呑

U+5451 "呑" CJK Unified Ideograph-# is a Chinese character (hanzi) that represents a variant form of the more common character "吞" (tūn), meaning "to swallow" or "to devour." Its structure consists of the radical "口" (mouth) at the top, combined with "天" (sky or heaven) below, though the component "天" is visually distinct from the standard "吞" character's "天" element. In historical and regional usage, "呑" appears as an alternative, non-standard glyph in certain classical texts and calligraphic styles, where it may carry the same phonetic and semantic value as "吞" but with a slightly differing stroke composition. This character is part of the CJK (Chinese, Japanese, Korean) unified ideographs block, which aims to encode shared characters across East Asian writing systems, though its use in modern writing is rare outside specialized or artistic contexts.
