Why this word is great
EXEAT — [Noun] A formal permission for temporary absence from a university, college, or religious institution. Its etymology is a command: borrowed from Latin exeat, the third-person singular present subjunctive of exire ("to go out"), used as an impersonal imperative meaning "let him/her go forth." Unlike "leave," a bland administrative term for authorized time away, or "furlough," which carries the bureaucratic heft of state or military service, an exeat is a minor sacrament of institutional release. It is the crisp, signed slip passed from a dean's hand; the embossed card permitting a seminarian to step beyond the garden wall; the brittle document that transforms containment into sanctioned release. It is liberty, but liberty with an expiration date, a small bureaucratic reprieve that, by its very granting, defines the walls one temporarily leaves behind.
