Etymology: "Confirmed" is the past tense and past participle of "confirm," so its story is really the story of the verb. The verb came into English through Old French "confermer," which in turn came from Latin "confirmare," meaning "to make firm, strengthen, establish." The Latin is built from "con-," meaning "together," and "firmare," "to make firm," which itself comes from "firmus," the source of the English "firm." So at its heart, to confirm something is to make it firm or solid, and the sense of "establishing as true" grew naturally out of that idea of strengthening. The Middle English forms "confirmen" and "confermen" show the word arriving in English through French, where the Latin root had already softened into "confermer." The English word has kept the sense of making something secure, whether a structure, an agreement, or a claim.
