A trencher (from Old French tranchier; "to cut") is a type of tableware, commonly used in medieval cuisine. A trencher was originally a flat round of bread used as a plate, upon which the food could be placed to eat. At the end of the meal, the trencher could be eaten with sauce, but was more frequently given as alms to the poor. Later the trencher evolved into a small plate of metal or wood, typically circular and completely flat, without the lip or raised edge of a plate. Trenchers of this type are still used, typically for serving food that does not involve liquid; the cheeseboard is perhaps the most common type in the West.
An individual salt dish or squat open salt cellar placed near a trencher was called a trencher salt.
A "trencherman" is one devoted to eating and drinking, often to excess; one with a hearty appetite, a gourmand. A secondary use, generally archaic, is one who frequents another's table, in essence a pilferer of another's food.
A "trencher-fed pack" is a pack of foxhounds or harriers in which the hounds are kept individually by hunt members and only assembled as a pack to hunt. Usually, a pack of hounds are maintained together as a pack in kennels.
"Turn the Trencher" was a traditional children's party game in which an adult spun a platter on its edge in the middle of a seated ring of children. The child whose name was called had to stand and run to catch the platter before it fell. Failure entailed a forfeit or minor ordeal. The game was current as late as the mid twentieth century.
In Virgil's Aeneid, trenchers are the object of a prophecy. In bk.3, Aeneas recounts to Dido how after a battle between the Trojans and the Harpies, Calaeno, chief of the Furies, prophesied to him (claiming to have the knowledge from Apollo) that he would finally arrive in Italy, but
Never shall you build your promised city
Until the injury you did us by this slaughter
Has brought you to a hunger so cruel
That you gnaw your very tables.
