secularism

The term secularism is built upon the Latin concept of saeculum, which originally denoted a long span of time, an age, or a generation. From this temporal sense, it evolved in Christian Latin to mean "the world" in contrast to the eternal church, giving rise to saecularis (worldly). The modern abstract meaning emerged during the Enlightenment, as the adjective "secular" came to describe institutions separate from religious control. By adding the Greek-derived suffix -ism in the 19th century, the word formed a noun naming the specific doctrine advocating for the separation of civil government and public life from religious influence, thus completing its journey from a term about time to one defining a key principle of modern governance.
