This spell could be used to prepare a receptacle for the placing of a piece of soul within it, thereby allowing the targeted object (or creature) to become a Horcrux. Horace Slughorn found such a concept unspeakable, claiming not to know what the spell was, nor did he wish to find out.
Behind the scenes
- Little, if anything, is known of this spell; it is possible, however, that it will be explained either in the Harry Potter Encyclopedia, or (since the former seems to have been cancelled), on Pottermore.
- The likelihood of the incantation to this spell being revealed is very low, as Rowling said that she could not "possibly tell [us]. Some things are better left unsaid." in an interview, on July 30th, 2007.
