Bye has multiple meanings, some related to sports. In golf, the holes of a stipulated course that are still unplayed after a match is finished are a bye. In cricket, a bye is a run made on a ball not struck by the batsman.
Bye is also used in the idiom “by the bye,” which means “incidentally” or “by the way.”
Several Spanish terms of farewell are now commonly used in English. Adiós means “good-bye.” The word is a contraction of a, which means “to,” and Dios, which means “God.” Hasta luego means “see you later.” In the role of the Terminator, Arnold Schwarzenegger, the current governor of California, popularized the expression hasta la vista, which means “so long” or “until we meet again.”
