Sperethiel is the language of the elves. A number of words from Sperethiel are present—as loan words—in Or'zet.
Sperethiel is described as a very complex language with a number of subtle variations enabling expressions of different levels of formality and rank between speakers, much as in Japanese.
Sperethiel is supposed to be a unique language isolate, related to no other language or family of languages. In reality, the authors of the Shadowrun game borrowed heavily from Irish for many of the words or phrases given as examples. E.g. Tír na nÓg and Tír Tairngire relate to concepts of Irish mythology. On the other hand, the word inventory is not very fleshed out, and many words or morphemes are not cognate with Gaelic, but are new combinations somewhat suggestive of that language.
