'enantiomerically' originates from the English word 'enantiomeric' with the adverbial suffix '-ally', where 'enantiomeric' is derived from 'enantiomer' and '-ic'. 'Enantiomer' comes from Greek 'enantios' meaning 'opposite' and 'meros' meaning 'part'.

'enantiomerically' was formed in modern English by adding '-ally' to 'enantiomeric', which itself was derived from 'enantiomer' (from Greek roots).

Initially, it meant 'in a way relating to enantiomers', and this meaning has remained consistent in scientific usage.
