About This Root
From Greek oxys (sharp, acid, keen). Oxygen was named 'acid-maker' (oxy- + -gen) because early chemists thought it was essential to all acids. Oxide and oxidize describe chemical reactions with oxygen. Monoxide specifies a single oxygen atom. Xerox borrows from the 'dry' sense of a related Greek word.
