Jasai is a modern American coinage with no established meaning. It is usually read as a blend of Jace or Jesse with Isai, the Spanish form of Jesse, which would give it the sense "gift"; the spelling also echoes the popular Josiah and Jasiah. The name made a remarkable jump in the United States, from number 1214 in 2024 straight into the top 1000 at number 439 in 2025, its first appearance on the list.
