Frida comes from the Old Germanic fríðr, meaning "peace," "beauty," or "beloved." It is the short form of names like Frederica, Sigfrida, and Astrid. In Scandinavia and Germany, Frida has been used continuously for over a thousand years.
The Mexican painter Frida Kahlo (1907-1954) made the name internationally famous. Her father was a German immigrant, and she was named Friederich Kahlo's daughter Frida. The name is rising in the West in the wake of renewed interest in her life and work.
Frida reduces to one — the number of singular peace.
