acronym

Definition

An abbreviation formed by the initial letters of other words.

Etymology

Borrowed from German Akronym, from Ancient Greek ἄκρον (ákron, “end, peak”) and ὄνυμα (ónuma, “name”), equivalent to acro- (“high; beginning”) + -onym (“name”). Modelled after Homonym and Synonym, first attested in German in the early 1900s and in English in 1940.
