'adamitism' originates from the name 'Adam', the first man in the Bible, combined with the suffix '-ism', indicating a practice or belief.

'adamitism' evolved from the concept of 'Adamites', a sect that practiced nudity as a return to the innocence of Adam.

Initially, it referred to the practice of nudity in religious sects, but over time it has come to symbolize any belief in returning to a state of innocence.
