The belief that religion should not play a role in government or public education, and that people can live without religious influence.
Secularism promotes the idea that laws and policies should be made without religious influence.
Secularism is formed from "secularis" (from Latin, meaning worldly or temporal) and the suffix "-ism" (meaning a doctrine or belief system). The term refers to the belief in the separation of religion from civic affairs and the state.
Think of 'worldly' ('secularis') to remember that 'secularism' means a belief system that focuses on the non-religious aspects of life.
