adverb [ip-soh fak-toh] by the fact itself; by the very nature of the deed: to be condemned ipso fact
What is the origin of ipso facto?
First recorded in English in the mid-1500s, ipso facto is an adverb that comes directly from the Latin phrase ipsō factō “by the fact itself, by the very fact.” Ipso facto is often used when the very fact that one thing occurs is a direct consequence of another, as in “Having won all the gold medals in the sport’s Olympic events, she was ipso facto the best gymnast in the world.” Latin factō is the ablative form of factum “deed, act, fact,” and ipsō is the ablative of ipsum “very, same, itself,” among other senses. Ipso appears in other Latin expressions used in English, especially in law, including eo ipso“by that very fact” and ipso jure “by the law itself.”
