Isabella
Meaning
"God is my oath," as the medieval form of Elizabeth that Spain, Portugal, and Italy made their own; the name of queens from Castile to England, and a four-syllable classic that softens to Bella, Izzy, and Isa
Goes by Bella, Belle, Isa, Izzy
Famously borne by Isabella Bird, one of the first women elected a Fellow of the Royal Geographical Society.
The story
Isabella began in the Middle Ages as the southern European form of Elizabeth, keeping its Hebrew meaning, God is my oath, while Spain, Portugal, and Italy made the sound their own. It became a name of queens: Isabella of Castile bankrolled the voyage of Columbus, and medieval England was ruled beside queens Isabella from France and Angouleme. In America it stayed far from fashion for a century, then climbed steeply from the 1990s and reached number one around the turn of the 2010s, just as readers were meeting Isabella Swan, the Bella of the Twilight books. The name was already rising before the vampires arrived, so they cannot take all the credit, but the timing of its final leap is hard to ignore. It has since eased only a little, a four-syllable classic that softens naturally to Bella, Izzy, and Isa.
