Etymology: "Defensio" is simply the Latin noun from "defendere," meaning "to ward off" or "to defend," built from "de-" (here meaning "off" or "away") and "-fendere," a verb meaning "to strike." The original sense was physical: a warding off of blows, or a fortification. Its meaning shifted toward legal and argumentative territory as Roman courts and rhetoric developed, so a defensio came to be a speech or written argument that answers an accusation. English took the word directly from Latin, and it appears in English as a learned term for a formal defence, most often in titles of works that answer criticism. Because it is a borrowed Latin form rather than a native English word, it has stayed largely confined to scholarly, legal, and literary contexts, where it carries the sense of a formal, reasoned rebuttal rather than a simple act of protecting oneself.
