Hors d'oeuvre may be served at the table, as a part of the sit-down meal, or they may be served before sitting at the table. Hors d'oeuvre prior to a meal are either stationary or passed. Stationary hors d'oeuvre are also referred to as "table hors d'oeuvre". Passed hors d'oeuvre are also referred to as butler-style or butlered hors d'oeuvre.
