  • I don't think this one is actually Lavoisier, but another really cool term from the same early-modern-chemistry course I took. It was the original term for oxygen (contrary to my original assertion on dephlogisticated), because of the current scientific theory of phlogiston, a substance the combination with which would produce fire. Pure oxygen supports combustion better than normal air; thus it was supposed to have more capacity to combine with phlogiston, and naturally this would be because it didn't have any in the first place.
