Eirwyn is a masculine given name of Welsh origin. It is the masculine form of Eirwen, a modern feminine name created in the early 20th century.EtymologyThe name derives from the Welsh elements eira "snow" and gwen "white, blessed", giving the meaning "white snow" or "blessed snow". The masculine form substitutes the feminine -wen suffix with the masculine -wyn, so Eirwyn can be interpreted as "white/blessed snow" (from confusion with gwyn "white, fair, blessed") or simply as the masculine counterpart of Eirwen.Notable BearersEirwyn George (1936–2026), Welsh poet, writer and author.Gwilym Eirwyn Jones (1922–1994), known as Eirwyn Pontshân, Welsh carpenter, entertainer, and nationalist.David Eirwyn Morgan (1918–1982), Welsh minister, journalist, and nationalist politician.John "Shôn" Eirwyn Ffowcs Williams (1935–2020), Welsh Professor of Engineering and Master of Emmanuel College, Cambridge.Variant FormA related name is Eurwyn (pronounced AYR-win), meaning "white/blessed gold" from Welsh aur "gold" and gwyn "white, fair, blessed". Notable bearers include the curator and author Eurwyn Wiliam.Cultural ContextBoth Eirwyn and its feminine counterpart Eirwen belong to a tradition of Welsh neologisms formed from natural elements. They emerged during the late 19th and early 20th centuries as part of a cultural revival that drew on the old Welsh poetic stock. The name remains distinctly Welsh in usage and reflects the grammatical gender distinction characteristic of the language.Meaning: "white snow" or "blessed snow"Origin: WelshType: First name (masculine)Usage regions: Wales
