Strong, virtuous, and honorable
Briannah is a modern elaboration of the Irish name Brianna, the feminine form of Brian. It is derived from the Old Celtic element 'bre', meaning hill or high, which metaphorically extends to mean noble or exalted. The 'h' ending is a stylistic American variation that adds a softer, more decorative visual appeal.
