U+513F "儿" CJK Unified Ideograph-# Unicode Character
U+513F "儿" CJK Unified Ideograph-# is a Chinese character that serves as both a standalone word and a common radical in East Asian scripts, particularly in written Chinese, Japanese, and Korean. As a standalone character, it is pronounced "ér" in Mandarin and primarily means "child" or "son," though it can also function as a suffix or a diminutive marker in various compounds, such as "儿子" (son) or "小孩儿" (little child). Its radical form, known as "儿" (er) radical, is often used at the bottom or right side of complex characters to imply a sense of human form, leg, or movement, as seen in characters like "光" (light) or "先" (before). Historically derived from a pictograph of a simple human figure, this character represents one of the fundamental components of the CJK (Chinese, Japanese, Korean) unified ideograph set, reflecting its deep integration into the structure and meaning of numerous East Asian words.
