The name
Leiðarljós is a guiding light.
Leiðar is the genitive of leið, a way or course. Ljós is light. The compound is the lamp you keep on a path. The binary is ljos.
Why it is not the first line
The door teaches the first success: write one claim, search it back. A stranger does not need the Icelandic before that works. The name stays on the brand, the lamp mark, and this page.
What the lamp is for
The seat writes only on Remember: and Prefer:. Nothing is mined from chat. A sitting opens the pack, the island, and the ticket. Finish writes what the work produced. That is the path the name points at.
Pronunciation
Approximate English: LAY-thar-lyohs. Icelandic ð is the voiced th in this. ljos is the same word without the path.
