The word "无名氏" is a three-character compound term formed through logical semantic combination: "无" means "without," "名" means "name," and "氏" is a classical term for a clan, family, or surname, often used as a respectful or formal reference to a person. When combined, the phrase literally translates to "a person without a name or surname," functioning as a fixed lexical unit to denote an anonymous or unidentified individual, typically used for authors, creators, or figures whose true identities are lost to history. Its formation follows the common Chinese morphological pattern of modifying a core concept ("氏" - person) with descriptive attributes ("无名" - nameless) to create a specific, culturally recognized meaning.
