Word Origin & History
toast (n.)
"a call to drink to someone's health," 1700 (but said by Steele, 1709, to date to the reign of Charles II), originally referring to the beautiful or popular woman whose health is proposed and drunk, from the use of spiced toast to flavor drink, the lady regarded as figuratively adding piquancy to the wine in which her health was drunk. The verb meaning "to propose or drink a toast" also is first recorded 1700. This probably is the source of the Jamaican and U.S. black word meaning "extemporaneous narrative poem or rap" (1962).
