Did you know?

Like the common words fact and factual, factitious ultimately comes from the Latin verb facere, meaning "to do" or "to make." But in current use, factitious has little to do with things factual and true—in fact, factitious often implies the opposite. The most immediate ancestor of factitious is the Latin adjective facticius, meaning "made by art" or "artificial." When English speakers first adopted the word as factitious in the 17th century, it meant "produced by human effort or skill" (rather than arising from nature). This meaning gave rise to such meanings as "artificial" and "false" or "feigned."
