Sortilege is a noun that refers to sorcery.
Taking its origin from the Latin word sortilegium (soar too LEDGE um) our word of the day goes back to the 14th century and initially referred to the divination of a person’s fate. More recently it refers to any form of sorcery.
When I predicted the joke dad would tell at thanksgiving dinner, people thought I had engaged in some kind of sortilege. But actually, the prediction didn’t come from supernatural sources, but from my memory. I was recalling all the past thanksgiving dinners where dad told the same joke.
