'alkoxy' originates from the combination of 'alkyl' and 'oxy,' where 'alkyl' refers to a type of hydrocarbon group and 'oxy' refers to the presence of an oxygen atom.

'alkoxy' was formed by combining the terms 'alkyl' and 'oxy' to describe a functional group in organic chemistry.

Initially, it meant a group containing an alkyl and oxygen, and this meaning has remained consistent in modern usage.
