What is the meaning of the name Cynyn ?

Cynyn is Welsh in Origin.

Cynyn is a rare Welsh masculine name from the Brythonic tradition. Its etymology is debated: some derive it from Welsh cyn, meaning “first” or “chief,” with the suffix -yn giving a familiar or diminutive sense (“little/young chief”); others link it to the Proto-Celtic root *kun- “hound,” making it a Welsh cousin of Irish Conán and Welsh Cynan. Both routes reflect themes of leadership and valour in early Celtic naming.

Medieval records show forms Cynyn and Cynin, and the name survives in Welsh hagiographical and place-name traditions (compare Llangynin, dedicated to Saint Cynin). Usage declined after the Middle Ages but appears occasionally in modern Welsh revival naming. Variants include Cynin and Cynan; Anglicized spellings such as Kynan occur, and Conan is a close Goidelic cognate rather than a direct variant. Though uncommon internationally, Cynyn offers a compact, traditional choice with deep Celtic roots.
