Usage
Plural word for ox The plural form of ox is oxen. This is one of the few remaining irregular nouns whose plural derives directly from its original pluralization in Old English. A similar change is made when pluralizing woman (women), man (men), and child (children). In some rare instances, ox is pluralized in the more conventional fashion as oxes, but this form is often considered incorrect and should be avoided.
