What does onymous mean?
Onymous is an uncommon formal adjective meaning that something bears a name, particularly the same name as another person or thing. Its most useful feature is its contrast with anonymous: an onymous subject has a name or identifiable name, while an anonymous one does not. The word can also suggest a deliberate pairing, as when two records are described as onymous because they concern people with identical names. This makes it useful in historical, genealogical, legal, and biological writing, where distinctions between identity, shared names, and missing names can matter. It should not be confused with synonymous, which concerns words or ideas having equivalent meanings, or with homonymous, which is more precisely limited to people or things bearing the same name. Although not obsolete, onymous sounds technical and is most appropriate when greater precision is intended.
adjectiveDenoting something that has a name, especially something that shares its name with another person or thing.

Where does onymous come from?
The word belongs to a family of English terms built from a Greek element meaning “name,” also underlying words such as anonymous, pseudonym, synonym, and autonym. The prefix in onymous conveys a relationship to naming, distinguishing it from anonymous, in which the corresponding prefix negates the presence of a name. English usage of this naming family grew partly through learned vocabulary in medicine, taxonomy, and other scholarly fields.
