What does eponymous mean?
'Eponymous' is an adjective used to describe either the person from whom something takes its name or, in more recent usage, the thing that bears that person's name. In the first and oldest sense, one might say that Marie Curie is the eponymous figure behind the Curie Institute, meaning the institute was named in her honour. In the second sense, common in music and publishing criticism, an 'eponymous album' or 'eponymous memoir' is one titled simply after its creator rather than given a separate title — what record shops often call a 'self-titled' release. Derived from Greek roots meaning 'upon' and 'name', the word entered English in the nineteenth century alongside its noun form, 'eponym'. It carries a formal, slightly scholarly tone and appears most often in journalism, biography, and arts criticism. Its flexibility across both directions of naming makes it a precise and economical word for writers.
(Of a person) being the person after whom something is named.
"The university's eponymous benefactor attended the opening ceremony."
This is the older and traditionally preferred sense.
(Of a work or creation) bearing the name of its creator or performer; self-titled.
"Their eponymous third album went platinum within months."
Widely accepted in contemporary usage but sometimes avoided in very formal writing in favour of 'self-titled'.
The word 'sandwich' comes from an actual eponym — the Earl of Sandwich — who reportedly demanded meat between bread slices so he could gamble without leaving the table.

Etymology of eponymous
'Eponymous' derives from the Greek 'eponymos', formed from 'epi-' ('upon') plus 'onyma' ('name'), literally 'giving one's name to something'. It was borrowed into English in the mid-nineteenth century, together with its related noun 'eponym', which refers to the person or thing whose name has been bestowed on another. The root 'onyma' also underlies other English words concerned with names, such as 'synonymous' and 'anonymous', making these useful cognates for learners.
