The 10th and also the 26th (and last) of the ruling stewards of Gondor (LotR/1039), possibly derived from the name of the Nandorin Elf Denethor. Its meaning (if any) as a Sindarin name is unclear; the elements of the Nandorin name do not have any clear Sindarin cognates.

Conceptual Development: The name of the last ruling steward was N. Denethor when he first appeared in Lord of the Rings drafts from the 1940s (TI/375).
