U+5728 "在" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

在

U+5728 "在" CJK Unified Ideograph-# is a fundamental logogram in the Chinese writing system, also used in Japanese and Korean, which primarily conveys the meanings of "to be at," "to exist," or "to be located" in a place or time. In Classical and modern Chinese, it functions both as a verb indicating existence and as a preposition marking location or ongoing action, as in "他在家" meaning "he is at home" or "他在学习" meaning "he is studying." It consists of the radical 土 (earth) on the bottom left and the phonetic component 才 (talent), reflecting its ancient derivation from a pictograph of a plant emerging from the ground. As a highly frequent character in East Asian texts, "在" is essential for expressing spatial and temporal relationships, and it is standardized in Unicode as CJK Unified Ideograph U+5728 across all major encoding systems.
