Meaning and history
Delyth is a modern Welsh feminine name derived from Welsh del, an adjective meaning “pretty,” “neat,” or “smartly presented.” The ending gives it the form of a personal name rather than changing the central sense. It belongs to the twentieth-century revival and creation of Welsh-language names and should retain Welsh pronunciation. Notable bearers include Welsh public-health advocate Delyth Morgan and Welsh politician Delyth Jewell. The name is distinct from similarly spelled non-Welsh forms.
