Etymology: Azotaemias is simply the plural of azotaemia, so the story belongs to the singular. Azotaemia is a medical term for an excess of nitrogenous waste compounds such as urea in the blood, and it is built from the Greek "azotos", meaning "lifeless" or "without life", combined with "haima", meaning blood. The name points back to the early chemistry of nitrogen. Nitrogen was once called "azote" in French scientific writing, a term coined to describe a gas that does not support life, because burning and breathing stop in it. The medical word was therefore formed by combining that chemical name with the Greek for blood, producing a label for a condition in which nitrogen-containing compounds build up in the bloodstream. The plural form simply counts separate instances or types of this condition, as medical writers do when discussing more than one case or kind.
