Halo is a modern American word name taken from the ring of light around a saint's head in religious art; the word goes back to the Greek halos, the "disk of the sun or moon", so the name means "ring of light". It joins Heaven, Nevaeh and Promise in the group of spiritual word names American parents have coined. Halo was virtually unused in 2000, entered the top 1000 in 2019, peaked at number 513 in 2024 and ranks number 613 in 2025.
