'amoral' originates from Greek, specifically the word 'a-' meaning 'without' and 'moral' from Latin 'moralis' meaning 'pertaining to manners.'

'amoral' changed from the Greek prefix 'a-' combined with the Latin 'moralis' and eventually became the modern English word 'amoral.'

Initially, it meant 'without morals,' and this meaning has largely remained the same in modern usage.
