UK: ˈʃeɪkʌp | US: ˈʃeɪkˌʌp
n. a radical reorganization or restructuring, especially in a business or political context

The term "shake-up" originates from the literal action of shaking something vigorously to rearrange or dislodge its contents (e.g., shaking a bottle). By the mid-19th century, it evolved metaphorically to describe disruptive changes in organizations or systems, emphasizing the idea of "stirring things up" to create renewal. The morpheme "up" adds a sense of completion or intensification, reinforcing the transformative nature of the action.
