This is one of those things that if you’re a fan, you’re probably already saying this each night, but anyway…
The Quenya translation is by J.R.R. Tolkien (published in Vinyar Tengwar #43).
Átaremma i ëa han ëa,
na aire esselya,
aranielya na tuluva,
na care indómelya
cemende tambe Erumande.
Ámen anta síra ilaurëa massamma,
ar ámen apsene úcaremmar
sív’ emme apsenet tien i úcarer emmen.
Álame tulya úsahtienna
mal áme etelehta ulcullo.
Násie.
