what is the meaning of taking the lord's name in vain

Most characters in the novels refer to him as "You-Know-Who" or "He-Who-Must-Not-Be-Named" rather than say his name aloud. In Harry Potter and the Deathly Hallows, a "taboo" spell is placed upon the name, such that Voldemort or his followers may trace anyone who utters it. By this means, his followers eventually find and capture Harry and his friends Ron Weasley and Hermione Granger.

According to the author, Voldemort's name is an invented word.[9] Some literary analysts have considered possible meanings in the name: Philip Nel believes that Voldemort is derived from the French for "flight of death",[10] and in a 2002 paper, Nilsen and Nilsen suggest that readers get a "creepy feeling" from the name Voldemort, because of the French word "mort" ("death") within it and that word's association with cognate English words derived from the Latin mors.[11]
