unsigned

Synonym discussion
Sense: adjective/1
All four words describe the absence of identifying information, but they differ in scope and formality. 'Unsigned' is the most concrete term: it refers specifically to the physical or digital absence of a signature on a document, letter, or artwork. 'Anonymous' is broader — it means the creator's name is unknown, whether or not a signature was ever present (e.g., an anonymous donation may come with a letter that is signed 'A Friend'). 'Unattributed' is more formal and common in academic or publishing contexts, referring to a quotation, idea, or work whose source is not credited. 'Unmarked' is the broadest of the four and can refer to any item lacking an identifying sign or label, not just textual or artistic works — for example, an unmarked police car or an unmarked grave. In everyday contexts, use 'unsigned' for documents and artwork, 'anonymous' when the creator's identity is deliberately hidden, 'unattributed' in formal or scholarly writing, and 'unmarked' for objects without any label at all.
Common collocations
Etymology
Formed in English by adding the prefix 'un-' (meaning 'not') to 'signed', the past participle of 'sign'. The verb 'sign' comes from the Latin 'signare' (to mark with a sign), which in turn derives from 'signum' (a mark, token, or sign). The sense of an athlete or musician 'unsigned' (not bound by a contract) emerged in the late 20th century, particularly in sports and entertainment journalism.
