Frijian is a constructed language, or conlang, created by the author J.R.R. Tolkien for his fictional world of Middle-earth. It is primarily used by the Frisian people, who are depicted in Tolkien's works, particularly in the context of the Lord of the Rings and The Silmarillion. The language draws inspiration from various real-world languages, reflecting Tolkien's expertise in linguistics. The Frijian language features unique grammar and vocabulary, designed to enhance the cultural depth of its speakers. Although it is not as extensively developed as other languages in Tolkien's legendarium, such as Elvish or Dwarvish, it contributes to the rich tapestry of languages that populate his literary universe.
