Origin

Old English ān, of Germanic origin; related to Dutch een and German ein, from an Indo-European root shared by Latin unus. The initial w sound developed before the 15th century and was occasionally represented in the spelling; it was not accepted into standard English until the late 17th century.

Usage

In modern English the use of one as a pronoun to mean ‘anyone’ or ‘me and people in general’, as in one must try one’s best, is generally restricted to formal contexts, outside which it is likely to be regarded as rather pompous or old-fashioned. In informal and spoken contexts the normal alternative is you, as in you have to do what you can, don’t you?.
