U+8A08 "計" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

計

U+8A08 "計" CJK Unified Ideograph-# is a logographic character used in multiple East Asian writing systems including Chinese, Japanese, and Korean, where it is commonly read as "kei" or "ge" in Japanese and "jì" in Mandarin. Its core meaning revolves around concepts of counting, measuring, planning, and calculation, as seen in words like 計算 (calculation) and 計画 (plan). The character is composed of the radical 言 (speech or words) on the left, indicating something related to verbal expression, and the phonetic component 十 (ten) on the right, which contributes both sound and the numerical idea of tallying. Historically, it reflects the ancient practice of using spoken words to record quantities or devise strategies, and it remains a fundamental component in modern vocabulary for mathematics, business, and project management across these languages.
