ýtarlegar

Could you confirm what ítarlegar refers to? Is it an Icelandic word, a proper noun, a technical term in a specific field, or a fictional concept you’d like described? If you’d like, I can draft a neutral, wiki-style article either about its real linguistic usage in Icelandic, or as a fictional concept with a defined meaning. Please specify the domain and any intended meaning, and I’ll produce a concise article under 300 words.
