This grammar describes the inner workings of the language of the Fwonnel Peninsula, known in its English translations as Fwonnel, Arojaunzan, or, most succinctly, Arojun. Contained within this 288-page paper are sections dedicated to Phonology, Phonetics, Morphology, Syntax, Example Texts, and various other elements of the world that I have created. Arojun is a moderately analytic language that features a Verb-Object-Subject word order, a pronoun-tense auxiliary system, and two orthography systems with historic significance. Connected to the language and included within this paper are sections on original Calendar Systems, Music Theory and Notation, Naming Traditions, Geography of the Fwonnel Peninsula, Religions, Two Dictionaries, a collection of common phrases important to learning the language and interacting with the people, and an in-depth look at the full political and linguistic history of the Fwonnel Peninsula. The Sample Text section includes several lines of interlinear glosses translating popular scenes from television shows from English(or Japanese) into Arojun, videos of which were posted to my YouTube Channel, Agma Schwa, over the course of the past year. This language, and in essence, the entirety of the fictional nation of El Fwonk Casanosia, has been building up to this point since 2007, when I was only seven years old. I may have needed to occasionally bend over backwards to make the less logical, yet emotionally significant, parts of this language and history reach a point of satisfactory suspension of disbelief, but I believe that it turned out wonderfully. Either way, this project took a great deal of effort, by far the largest project that I have worked on in my life.
