Eḥad Mi Yodea has a place in Seder tables throughout Arda, and in many communities it was read in translation. This translation into Quenya is necessary for any good Lothlórien sedarim. But to be serious, Quenya was one of several languages developed by J.R.R. Tolkien. It serves as the sacred ancestral language of the Noldorin elves in the Middle-Earth legendarium. The editor here has developed this adaptation of the well-known seder table-song Eḥad Mi Yodea into Quenya, with thanks and credit to the experts at elfdict for their help. He has also transcribed it into a home-brewed transcription system into Hebrew script also used for his Min Yacincë translation of Ḥad Gadya.
