Etymology: Normokalemia is a medical coinage, built from two pieces that were assembled deliberately rather than inherited from ancient usage. The first part, "normo-", comes from Latin "norma," meaning a carpenter's square or rule, and in English it means "normal." The second part is "kalemia," a modern formation meaning "potassium in the blood." It follows the pattern of "hyperkalemia" and "hypokalemia," and it draws on "kalium," the Neo-Latin name for potassium, which itself comes from Arabic "al-qali," the word for plant ash used as a source of alkali, combined with the suffix "-emia," from Greek "haima," "blood." Put together, the word states its own meaning: it describes a blood potassium level within the normal range. Because clinicians needed a term that could sit alongside its opposites, the coinage produced a matched set, so a doctor can name a level as high, low, or normal using parallel forms.

Antonyms: hypokalemia, hyperkalemia
