What does confirmed mean?
"Confirmed" serves two closely related roles in English. As the past tense and past participle of the verb "confirm," it means that something has been verified, established as true, or made definite — a rumor can be confirmed, a flight booking can be confirmed, and a diagnosis can be confirmed by tests. The word carries an air of authority and finality: once information is confirmed, doubt has been formally removed. It also functions as an adjective describing someone so thoroughly set in a belief, habit, or identity that change seems impossible — a "confirmed bachelor" will never marry, and a "confirmed optimist" always expects the best. This adjectival use adds a note of permanence, even inevitability, to the description. Common across journalism, science, medicine, and everyday administration, "confirmed" is a versatile word whose connotations range from rigorous verification ("confirmed findings") to unshakable disposition. Its Latin root, meaning "to make firm," underlies both senses.
Established the truth, accuracy, or validity of something; made an arrangement or decision definite.
"The committee confirmed his appointment unanimously."
Frequently used in passive constructions: "it was confirmed that..."
Firmly settled in a habit, belief, or characteristic; long-established and unlikely to change.
"She was a confirmed tea drinker who never touched coffee."
Usually appears attributively before the noun it modifies.
A "confirmed bachelor" was once such a fixed phrase that Victorian society used it as polite shorthand for a man who would never marry — no further explanation required.

Etymology of confirmed
"Confirmed" derives from the Latin "confirmare," formed from "com-" (an intensifier) plus "firmare" ("to make firm"), itself from "firmus," meaning firm or strong. The verb entered English via Old French "confirm(er)" in the medieval period, with the past participle "confirmed" following the same path. Cognates include French "confirmer," Italian "confermare," and Spanish "confirmar," all from the same Latin source, which also gave English the related words "firm" and "affirm."
