While the language is fictional, it's been used in a variety of ways throughout the series:
* Written language: Hylian appears on signs, maps, and in-game items.
* Spoken language: While the characters don't actually speak in the Hylian language, it's used for their written dialogue and in some promotional materials.
* Translation: Fans have created translations of the Hylian language, trying to decipher the symbols and apply meaning to them.
It's important to note that the Hylian language is not meant to be a real language, but rather a visual element that adds to the world-building and mystique of the Zelda universe.
