Cognate with Scots allane (“alone”). Compare also West Frisian allinne (“alone”), Dutch alleen (“alone”), German allein (“alone”), Danish alene (“alone”). More at all, one.

- one and once are pronounced differently from the related words alone, only and atone. Stressed vowels often become diphthongs over time (Latin bona → Italian buona and Spanish buena), and this happened in the late Middle Ages to the words one and once, first recorded ca 1400: the vowel underwent some changes, from ōn → ōōōn → wōn → wōōn → wŏŏn → wŭn.
- By one's self, solitary.
- I can't ask for help because I am alone.
- Apart from, or exclusive of, others.
- Considered separately.
- Without equal.
