Count: 0. There are no attested Norse gods whose canonical names begin with the letter C in primary sources such as the Poetic Edda, the Prose Edda, the sagas, or the skaldic corpus. Note that Old Norse spelling and modern scholarly practice use K for the /k/ sound, so names that might look like they start with C in casual English lists are rendered with K in reliable editions and glossaries.

Understand why this specific criterion returns no results. Rely on the linguistic facts of Old Norse: the Latin letter C is not native to Old Norse orthography and appears only rarely in later Latin or English transcriptions. Recognize that many apparent C‑names come from other traditions (for example, Celtic deities like Cernunnos) or from later Anglicizations of Norse‑associated historical names (for example, “Cnut” for the king Knut/Cnut, who is not a god). Expect accurate reference works (Poetic Edda, Prose Edda, Simek, Orchard) and A–Z glossaries to list K‑initial names instead: Kvasir, Kári, and Konr are examples of well‑attested figures that explain why a C‑list is empty.

Consult relevant letters and the full A–Z index instead of a C page. Use the K page for deities and figures with the /k/ sound, and consult standard secondary sources (Rudolf Simek, Andy Orchard) for reliable attestations and spellings. Treat any “C” entries found online with skepticism and verify them against primary texts and reputable academic glossaries.
