Etymology: "Addons" is the plural of "addon," a noun formed by taking the phrasal verb "add on" and turning it into a noun, a process linguists call deverbal formation. Its meaning, a modular enhancement that plugs into an existing system, grew naturally from the verb's sense of attaching something to something already in place. The plural is simply the regular "-s" ending added to the noun, so "addons" refers to more than one such extension. The word is a compound in spirit but was written as a single unit, which is why it appears as "addon" rather than the two-word "add on" in its noun form.

Synonyms: extensions, supplements, additions
