Kairo
Meaning
variant spelling of Cairo, from Arabic al-Qahirah, 'the victorious'
The story
Kairo is Cairo with this century's favorite letter swapped in, and underneath the K sits an Arabic magnificence: al-Qahirah, the victorious, the name the Fatimids gave their new capital a thousand years ago. As an American baby name it is nearly brand new: about 50 in the 1990s, 210 in the 2000s, 2,600 in the 2010s, and already 8,700 so far this decade, more than triple the full 2010s with years to run. It rides two waves at once, the K-respelling current that carried Karter and Malakai, and the place-name register where Milan also climbs; a family gets a world city, a victory built into the etymology, and a spelling that marks the choice as deliberate. In our records it goes to boys about 11,200 to 300. The city on the Nile has outlasted a millennium of rulers; the name is just getting started.
