Yrsa

The exact meaning of Yrsa has been lost to history, but theorists have come up with two possible explanations. The first, more likely option, is that Yrsa is a younger variant of the name Ýrr, meaning "mad" or "furious" or "wild". The other theory is based on Yrsa's similarities to Ursa, Latin for "bear", and suggests Yrsa comes from an Old Norse word that means "she-bear".

Pronounced ER-suh.
