Etymology: Hyperacidity is one of those words built almost entirely from Greek parts, with the prefix doing most of the work. The prefix "hyper-" comes from Ancient Greek "hyper", meaning "over" or "above" or "beyond", and it traces back through Proto-Hellenic to the ancient Indo-European root for "up" or "over". Attached to "acidity", the sharp, sour quality of a substance, it describes a condition where there is more of that sourness than normal. The sense of "excess" carried by the prefix is the whole point of the word. English already had "acidity" for sourness in general, and "hyper-" was a productive prefix for building technical terms about surplus, such as "hyperactive" or "hypertension". Combining the two produced a term for too much acid, most often in the stomach, where it causes discomfort. The word is a plain compound with no notable person or story behind it, so its meaning is simply what its parts say.
