'deoxygenated' originates from the prefix 'de-' meaning 'removal' and 'oxygenate' from 'oxygen', which is derived from the Greek word 'oxys' meaning 'sharp' or 'acid' and 'genes' meaning 'producer'.

'deoxygenate' transformed from the combination of 'de-' and 'oxygenate', eventually becoming the modern English word 'deoxygenated'.

Initially, it meant 'to remove oxygen from something', and this meaning has largely remained the same in modern usage.
