U+9808 "須" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
須
U+9808 "須" CJK Unified Ideograph-# is a Chinese character that primarily means "must," "necessary," or "to need," and it is also used in Japanese as a component of words like "必須" (hissu) meaning "essential." Historically, it derives from a pictograph of a beard or whiskers, reflecting an older meaning related to facial hair, though this usage has largely been supplanted by the more common character "鬚" in modern Chinese. In East Asian languages, "須" appears in various contexts, from expressing necessity in Classical Chinese texts to forming compound words in contemporary Japanese and Korean.
