Cornish names come from Kernewek, a Brythonic Celtic language closely related to Welsh and Breton, and from long contact with English. Given names often reflect medieval local saints and hagiography: Piran, Petroc, Ia, Neot, Kea, Senara, Morwenna. Cornish forms of pan‑European names also appear, such as Jago (James) and Tamsin (Thomasina), and the Cornish-origin Jennifer/Jenifer (from the Gwenhwyfar/Guinevere tradition). Common linguistic features include initial gw‑ (Gwenno, Gwennap in toponyms), the endings ‑en/‑enna (Elowen, Lowenna, Morwenna), and historical ‑oc/‑ek in saintly names (Petroc). Vowel digraphs ow and ew are frequent. Surnames often begin with Tre‑, Pol‑, or Pen‑, reflecting place‑name origins in Cornwall.
Traditional practice mixed Cornish and English naming, with biblical names widespread from the medieval period onward. A modern revival since the late 20th century has restored older saints’ names and introduced vocabulary‑based choices, notably nature and abstract nouns in Cornish (Elowen “elm,” Lowenna “joy”). Usage and spellings vary because the revived language has multiple standard orthographies. Overall patterns are hybrid, shaped by Celtic (Cornish/Welsh/Breton) forms and sustained English influence.
