A trope in modern fantasy/science fiction is the idea of a central language (often called The Speech) that is the root of all languages, and in some cases the true describing words that made the universe.
Unifying characteristics of this language in many books include: A popular example of this is found in the Young Wizards series of novels by Diane Duane.
All creatures and things understand and, to a degree, can speak the Speech intuitively, but specifically, it is the wizards who use it as their primary language and means of performing their works of magic.
Describing something inaccurately in the Speech may result in catastrophic effects (including changing the nature of the thing or being therein misdescribed); therefore, wizards are advised to never curse or lie in the Speech.
The written characters of "The Speech" are described in several of the books as resembling Arabic, and in Deep Wizardry, Nita's father mistakes the writing on the title page of Nita's Manual for Arabic letters.
