The word radical traces back to the Latin radix ("root"), reflecting its core idea of fundamental or foundational change. Originally used in botany and mathematics to describe roots, it later evolved metaphorically to denote extreme or revolutionary ideas (early 19th century). The shift from literal "root" to "thoroughgoing reform" mirrors the concept of addressing issues at their source.
