The story of the word

Lavoisier's circle rebuilt chemical naming in 1787 and needed a word for what a metal becomes when it burns. They cut it out of oxygène, itself ὀξύς, sharp or sour, plus a producing element, because Lavoisier believed oxygen was the thing that made acids acidic. He was wrong; hydrogen does that job. The mistake is now stamped on every oxide in the periodic table.
