"an official announcement or report," 1852, from French communiqué, originally past participle of communiquer "to communicate" (14c.), from Latin communicare "impart, inform" (see communication). Originally the heading of official statements from the French government. Fowler says better, if it must be used in English, to print it with the accent.
