'Euro-skeptic' originates from the combination of 'Euro,' referring to Europe or the European Union, and 'skeptic,' from the Greek word 'skeptikos,' meaning 'inquirer' or 'doubter.'

'Euro-skeptic' emerged in the late 20th century as a term to describe individuals or groups questioning the European Union's policies and integration efforts.

Initially, it referred to general skepticism towards European integration, but now it often implies opposition to specific EU policies.
