Nerys

Nerys is a Welsh name that emerged relatively recently in the history of Welsh nomenclature. It is believed to be a modern coinage, derived from the Welsh word 'annerch' meaning 'to greet' or 'to address', with the 'an-' prefix often dropped in common usage, leaving 'erch' which could be interpreted as a form of address. More commonly, it is understood as a diminutive or pet form of the name Agnes, particularly in its Welsh form, Nest. Nest itself is a medieval Welsh form of Agnes, which means 'pure' or 'holy'.

The name gained significant popularity in Wales during the 20th century, becoming a well-loved and distinctly Welsh feminine name. Its elegant sound and clear Welsh identity have contributed to its enduring appeal within Wales, though it remains less common outside of Welsh-speaking communities.
