Insults in Kanshi are completely harmless for most other languages. Since the high elves of the islands are extremely courteous, the mere omission of a homage counts as a deadly insult, which at least leads to a wounded sense of honor. Nevertheless, even in Kanshi there are some phrases that are in no way inferior to the more common languages in their creativity.
Like many elven languages, the Kanshi has a certain melodic beauty that could tempt many people to want to learn the language. However, this project is very difficult in any case, because it depends on the exact emphasis of the words and very few people have the patience to actually learn and master this language. However, even less are able to use the language in such a way that a high elf who is powerful enough for them would condescend to answer.
