U+662F "是" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

是

U+662F "是" CJK Unified Ideograph-# is a fundamental Chinese character used in both modern and classical Chinese writing, where it primarily functions as a copula meaning "to be" in statements of equivalence, identity, or existence, such as in the sentence "他是学生" meaning "He is a student." Its origins trace back to ancient oracle bone script, where it originally depicted a foot (止) above or reinforcing a sun (日), conceptually suggesting correctness, affirmation, or alignment with truth, a meaning that evolved into its modern grammatical role. In addition to Chinese, this character is also used in Japanese kanji and Korean Hanja with similar semantic and phonetic values, often appearing in compound words like "是非" (right and wrong) or "是否" (whether or not).
