llyr

Llŷr, also rendered Llyr, is a figure in Welsh mythology associated with the sea. In medieval Welsh literature, he is presented as a powerful progenitor and sea-figure whose name is closely linked with the word for sea in the Welsh language.

In the Mabinogi, the four branches of the mythic tradition, Llŷr is described as the father of Branwen and Manawydan. The tales of Branwen ferch Bran recount a marriage alliance with Ireland and its breakdown, while the adventures of Manawydan uab Llyr follow the later fortunes of Branwen's husband and the kingdom. Through these characters, Llŷr functions as a parental figure and as a personification of the sea, whose realm borders the islands and serves as a source of peril and homecoming.

Etymology and role in tradition: The name Llŷr itself is cognate with the Welsh word llyr, meaning sea; as a legendary figure, he is sometimes treated as a sea god or king of the drowned world. Scholarly discussions sometimes draw parallels with Irish Lir and the later sea-god Manannán mac Lir, but direct correspondences are debated.

Legacy: In modern Welsh culture, Llŷr is recognized in literature and place names. The name is used for people and institutions; the sea imagery persists as a symbol of origin and boundary.
