Etymology

It is borrowed from Late Latin anonymus,[2][3][4] from Ancient Greek ἀνώνυμος (anṓnumos, “without a name”), from ἀν- (an-, “without”) and onuma, the Aeolic form of ὄνομα (ónoma, “name”) (see name),[3][2][5] with -ous.[2][5]

Earliest recorded meaning

Nameless, of unknown name: 1601, in Holland's translation of Pliny;[2][6] about 1600 in Etymonline.[3] MWU dates a sense to 1563.[7]

Semantic evolution

As a noun, a person whose name is not given, it is from 1603.[6] Of writings, published without an author's name or of unknown authorship, it is from the 1670s (1676 in the OED).[3][6] Lacking individuality or distinctive features is a modern sense.[8][9] Anonymity is a 19th-century formation.[4]
