[ Usage notes

• For what reason are the English words one and once pronounced so, while other words derived from one, like alone, only and atone, pronounced with a long o? Stressed vowels often became diphthongs over time (Latin bona → Italian buona and Spanish buena). A similar thing happened in the late Middle Ages to the English words one and once, first recorded circa 1400. The vowel sound underwent some changes, such as thee pronunciation (from ōn → ōōōn → wōn → wōōn → wŏŏn → wŭn).
