Kysir

Likely another member of the Kaiser, Kyzer, Kaizer, and Kyzir family, Kysir feels especially trendy. It contains the cool Kye sound, has a regal meaning (a la Rex, Kingston, Kingsley, Prince, Reign, Royal), starts with a K, and blends in the element Sir.

Based on the German "Kaiser", the Arabic Qaisar, the Latin Cesar, and the Arabic Khadir, NFL player Kyzir White likely helped popularize this form. It tripled in popularity between 2023 and 2024 when it was chosen for 30 babies.

Pronounced KY-zur.

As of October 2026, Kysir ranked #4201 for boys in US births in 2025 SSA, peaked at #3844 for boys in 2024.
