Kajira is the term for "slave-girl" in John Norman's Gor novels. Slaves in the Gorean lifestyle will refer to themselves as kajirae. The phrase "la kajira" is said to mean "I am a slave-girl" in the main Gorean language (the most widely-spoken lingua franca in the known regions of the planet Gor); this is one of the few complete Gorean-language sentences given in the Gor novels.
The word is usually seen in the feminine form "kajira" (plural "kajirae"), as most slaves in the Gorean lifestyle are female; the masculine forms are "kajirus" and "kajiri" (following the rules of nominative adjective morphology in the Latin language, as seen also with words such as "alumnus"/"alumna", etc.). The construction "kajiras" is incorrect, but is occasionally seen in third-party writing
