late 14c., "state of extreme dread or suspense," also "a half-conscious or insensible condition, state of insensibility to mundane things," from Old French transe "fear of coming evil," originally "coma, passage from life to death" (12c.), from transir "be numb with fear," originally "die, pass on," from Latin transire "cross over" (see transient). French trance in its modern sense has been reborrowed from English. As a music genre, from c.1993.
