Signy, of Old Norse origin, is a rare and unique female given name that means "victory." It is derived from the element "sigr" which signifies victory, suggesting strength and triumph. In Scandinavian folklore, Signy is known as one of the daughters of King Siggeir of Gautland, a character in the Volsunga saga. The name was popularized by the works of the poet Johan Ludvig Heiberg in the 19th century and has since been used sparingly, contributing to its distinctive character today.
The name Signy experienced fluctuations in popularity over the years, with a notable increase in usage between 2021 and 2022, compared to the previous periods.
