Joan is both a feminine form of the personal name John given to girls in the Anglosphere as well as the native masculine form of John in the Catalan-Valencian and Occitan languages. In both cases, the name is derived from the Greek via the Latin Ioannes and Ioanna, and is thus cognate with John and related to its many forms, including its derived feminine forms.
