Did You Know?
Adventitious is an adventitious word: it comes to English from the Latin adventicius, meaning "coming from outside." This, in turn, comes from "adventus," the past participle of the verb advenire, meaning "to arrive" or "to happen." That verb is also a source of several other English words, including "advent" (which, in its uncapitalized form, can refer to any coming or arrival), "adventure" (a word whose earliest sense was "chance happening"), and "avenue" (a means of arrival).
