'antinomianism' originates from Greek, specifically the word 'antinomia,' where 'anti-' meant 'against' and 'nomos' meant 'law.'

'antinomia' transformed into the Medieval Latin word 'antinomianismus,' and eventually became the modern English word 'antinomianism.'

Initially, it meant 'against the law,' but over time it evolved into its current meaning of 'belief in the irrelevance of moral law under the gospel.'
