"Ethanol" is the systematic name defined by the International Union of Pure and Applied Chemistry (IUPAC) for a compound consisting of alkyl group with two carbon atoms (prefix "eth-"), having a single bond between them (infix "-an-"), attached functional group-OH group (suffix "-ol"). 

The "eth-" prefix and the qualifier "ethyl" in "ethyl alcohol" originally come from the name "ethyl" assigned in 1834 to the group - by Justus Liebig. He coined the word from the German name "Aether" of the compound -O- (commonly called "ether" in English, more specifically called "diethyl ether"). According to the Oxford English Dictionary, "Ethyl" is a contraction of the Ancient Greek αἰθήρ (aithḗr, “upper air”) and the Greek word "" ("hyle", substance).
