What is the meaning of the name Cennydd ?

Cennydd is Welsh in Origin.

Cennydd is a Welsh masculine name (pronounced KEH-nith; Welsh dd = voiced th) best known from Saint Cennydd, a 6th‑century hermit associated with Llangennith on the Gower Peninsula. Its exact meaning is uncertain; scholars treat it as a native Brittonic/Welsh formation whose original elements are now opaque. Although it has often been equated with the English/Scottish Kenneth, that linkage reflects later Anglicization rather than true etymology.

The name appears in medieval sources with spellings such as Cenydd, Kened, and Kenith, and was Latinized in various ways. Use declined after the Middle Ages but saw modest revival alongside Welsh cultural renewal in the 19th–20th centuries; it remains rare today. Variants and related forms include Cenydd (single n) and the place-name Llangennith preserving the saint’s cult. Note that Kenneth and Kenny are generally from Scottish Gaelic Coinneach/Cináed and are only historically assimilated, not genuine Welsh variants.
