Sulwen Origin and Meaning

The name Sulwen is a girl's name meaning "white Sunday".

Sulwen is the feminine form of Sulwyn, a Welsh name associated with the Christian festival of Pentecost. It combines the elements of Dydd Sul (meaning Sunday) and gwyn (meaning white or holy), and translates literally to “white Sunday”.

It is also theorized that the name could combine Sul, meaning sun, with -wen (meaning white and fair), to give the meaning "fair sun", making nickname Sunny feel just apt.

While Sulwen is the official feminine form, Sulwyn has also been used on girls - particularly as a middle name.
