your stomach acid staging a hostile takeover of your esophagus, named after the wrong organ entirely

means A burning sensation behind the breastbone caused by stomach acid backing up into the esophagus, despite having nothing to do with your actual heart.

from A plainspoken English compound of "heart" and "burn," dating back centuries to a time when "heart" loosely meant the whole chest-and-stomach region rather than the specific blood-pumping organ. The burn felt high in the chest, so people blamed the heart — and the name stuck even after anatomy sorted out which organ was actually misbehaving. The same vague "heart" lurks in older expressions for indigestion and lingers in the Latin-derived medical term "cardialgia," where the Greek root for heart (kardia) was likewise used for the upper stomach.
