Pronounced as (IPA)

/wʌn(t)s/

From Middle English ones, from Old English ānes, a remodelling (after ān (“one”)) of ǣnes, itself an extension of ǣne (“once”) with the genitival suffix -es. Compare Old Saxon ēnes (“once”), Old High German eines, einēst (“once”), modern German einst (“once”). More at one (including regarding the development of the pronunciation) and -s.
