What's the "een" in Halloween?
early 15c., "version, translation, a form of a literary work;" 1550s, "act of publishing," from French édition or directly from Latin editionem (nominative editio) "a bringing forth, producing," also "a statement, account," from past participle stem of edere "bring forth, produce," from ex- "out" (see ex-) + -dere, comb. form of dare "to give" (see date (n.1)). "It is awkward to speak of, e.g. 'The second edition of Campbell's edition of Plato's "Theætetus"'; but existing usage affords no satisfactory substitute for this inconvenient mode of expression" [OED].
