Usage notes
The "inexpressible" sense of untold is pragmatic; it is determined only by context. This use is common in Lovecraftian and Gothic Horror genres, where stories focus mainly on incomprehensible or indescribable things, and so are rendered inexpressible by their characters. Typically, these characters will speak of untold "treasures" or "suffering", or other things of indefinite but immense magnitude.
