1911 Encyclopædia Britannica/Toast

TOAST, a slice of bread scorched brown on the two surfaces by the heat of a fire. The word was borrowed from the O. Fr. taste, Lat. torrere, tostum, to scorch, burn. It was formerly the custom to have pieces of toast floating in many kinds of liquor, especially when drunk hot. It is said to be from this custom that the word is used of the calling upon a company to drink the health of some person, institution or cause (see Health).
