Dyliss is Welsh in Origin.

Dyliss is a modern English respelling of the Welsh name Dilys, derived from the Welsh adjective dilys meaning “genuine, sincere, authentic” (also “valid, legitimate” in legal usage). Used primarily as a feminine given name in Wales, Dilys began appearing in parish and civil records in the late 19th and early 20th centuries amid a wider revival of Welsh-language names. The reputation of cultural figures such as poet Dilys Cadwaladr and critic Dilys Powell kept the traditional form visible through the mid-20th century.

Dyliss preserves the same pleasing two-syllable rhythm while clarifying the final -s sound for English readers. Rarer than its source form, it occurs across the UK, North America, and Australia as a contemporary twist with vintage roots. Variants and related spellings include Dilys (standard), Dylis, Dyllis, and Dillis; common nicknames are Dil and Dilly. The core meaning evokes honesty, authenticity, and heartfelt sincerity.
