late 14c., attested in Anglo-L. from mid-13c., via O.Fr. almanach or M.L. almanachus from Spanish-Arabic al-manakh "calendar, almanac" (occurring nowhere else in Arabic), possibly ult. from Late Gk. almenichiakon "calendar," probably of Coptic origin. This word has been the subject of much speculation; its central syllable may be from or influenced by the PIE root of Mod.E. moon and month.
