Other Origin(s):Greek, Latin
Meaning:Earth, keeper of the earth; Pure; Rejoice
Kaj is a masculine name whose minimalist look betrays a complex etymology. Predominantly Danish in origin, Kaj is often defined as "earth," sometimes elongated to "keeper of the earth." Others posit Kaj as a variation of Kaia, a Scandinavian variant of the Greek Katherine, which earns Kai the meaning of "pure" and its many related virtuous qualities. Finally, Kaj may also lay claim to the Latin name Caius, meaning "rejoice," imbuing the grounded name with an air of gravitas.
