Etymology: "Haema" is the Greek word for blood, "haima" in Attic and Ionic, and it is the stem behind the English prefix "haemo-" used in medical terms like "haemoglobin" and "haemophilia". The Greek noun is ancient, and its stem gave English a whole family of blood-related coinages, mostly built in the 19th and 20th centuries from classical roots rather than from ancient medical texts. In English the spelling "haem" or "heme" appears mainly as a combining form. The standalone noun "haema" is rarely used on its own. Its specialised medical sense comes from the way scientists have borrowed the Greek root to name blood components and blood disorders, so most readers meet it inside longer words.
