Forum:Quenya Translation?

Note: sorry anout my English.

I very liked the song "Glamdring" by Howard Shore in The Lord Of The Rings: The Two Towers, and in a part of the song they said a few times "METTANNA" and I know it's in Quenya. I spent a few hours trying to find the translation of this word but I didn't found it. Is there someone in this world that know the translation of that word?

p.g I know the translation of all the song but I didn't understand the meaning of that word.

Thank you
