Gnommish
Gnommish is the language of the fairies, which not only has a practical role within the story, but also peppers the margins of the original “Artemis Fowl” novel. This is basically a secret code for fans to decipher, allowing them to read hidden messages that tease the next book in the series. Here’s hoping that the movie puts special Easter Eggs and messages everywhere, so that fans have something to pore over when “Artemis Fowl” reaches a home release.
