mældur

Could you clarify what you mean by "mældur"? It could refer to different things (an Icelandic adjective meaning "measured/recorded," a proper name, or a fictional concept). Do you want a real-world, language-focused entry (linguistic usage and etymology), a geographic or historical entry, or a fictional/placeholder concept? If you’d like, I can also draft a concise, neutral stub in under 300 words once you specify the intended sense.
