Etymology
Etymology Information

'enantiomer' originates from modern scientific coinage ultimately derived from Greek: 'enantios' meaning 'opposite' and 'meros' meaning 'part'.

Historical Evolution

'enantiomer' was adapted into modern chemistry vocabulary (via German 'Enantiomer' in the 19th/20th century) from the Greek components and formed into the New Latin/International scientific term 'enantiomer'.

Meaning Changes

Originally built from elements meaning 'opposite part', it came to denote specifically a molecule that is the non-superimposable mirror image of another molecule.
