Yeaflon language is extremely complex and hard to translate. There are three main dialects and learning even one of them is near impossible. Some think that due to their high intelligence, and how hard Vulch was to survive on in the beginning, helped to form the complex languages. As the Yeaflon usually have to translate to be understood, they usually appear very proper and unemotional. Because of translation issues it is easy for a Yeaflon to accidentally appear rude when that was never the intent.
If a Yeaflon wishes to learn another language they have to endlessly repeat phrases, words, and basic sounds. Once they do learn a language, none of their unique learning process can be detected.
