A radical change, a transformation. Shakespeare coined this cliché in The Tempest (1.2): “Nothing of him that doth fade, But doth suffer a sea change Into something rich and strange.” Nearly four centuries later, J. A. Jance used it in Devil’s Claw (2000): “For the very first time . . . she had called her future son-in-law Butch instead of Frederick. It indicated a sea change in her mother’s attitude, and that was pretty damned wonderful, too.”
