In linguistics, an oxytone (from Greek ὀξύς (oxys) meaning "sharp" and τόνος (tonos) meaning "pitch" or "tone") refers to a word whose stress is on its penultimate syllable (i.e., the syllable before the last one).<br><br>A proparoxytone is a type of oxytone word that ends in a secondary stress accent, with its main stress falling on the antepenultimate syllable (i.e., the syllable before the penultimate one).<br><br>In other words, a proparoxytone is a word that has a weak stress on the last syllable, and a stronger stress on the third-to-last syllable.
