Joan of Arc’s first name in the language of her trial records was Jehanne.
The surviving condemnation-trial records were written in medieval French and Latin, and they commonly render her given name as Jehanne. This spelling reflects medieval orthography, when names did not always have one fixed modern form.
Modern French usually uses Jeanne d’Arc, while English uses Joan of Arc. The variant Jehanne appears in historical documents and in scholarly discussions of the trial, including forms such as “Jehanne la Pucelle,” meaning Joan the Maid.
The spelling should not be confused with a different person. Jehanne, Jeanne, Joan, and Johanna are language-specific or historical forms connected with the same woman. Her family name was not consistently used in the modern way during her lifetime.
