Nansy

Nansy is a variant of Nancy, which itself is a medieval diminutive of Agnes or Annis. The name Agnes comes from the Greek 'hagnos' meaning 'pure' or 'holy'. However, Nancy became strongly associated with the Hebrew name Hannah (meaning 'grace' or 'favor') through its French diminutive form, Anne. Over time, Nancy evolved into a standalone name, and Nansy is a less common spelling variant.

The name gained significant popularity in English-speaking countries, particularly from the 18th century onwards. Its simple, sweet sound contributed to its widespread use. The variant spelling 'Nansy' is less common and might be a phonetic interpretation or a deliberate stylistic choice.
