Etymology: Ancient Greek grammarians needed a way to describe words stressed three syllables from the end, and they built one by stacking prefixes onto the word for "sharp" or "high-pitched." "Oxýtonos" (ὀξύτονος) meant a word with its accent on the last syllable, literally "sharp-stressed," from "oxýs," sharp, and "tónos," tone or stress. "Paroxýtonos" (παροξύτονος) moved the accent one syllable back, and "proparoxýtonos" (προπαροξύτονος) moved it back once more, with "pro-" meaning "before" in the sense of "further back." The English word was borrowed directly from this Greek term, so its structure is essentially a description of where the stress falls. The Greek coinage also explains why the word is so unusual in English. Its ancestor was a technical label for a feature of Greek pronunciation, and the same mechanical logic carried over when scholars adopted it for their own languages. Its neighbours in the family, "oxytone" and "paroxytone," follow the same pattern, so the word reads like a ladder counting back from the final syllable.
