If anyone can help me out, I am working on a little project and would like the following quote from the movie translated into Quenya:

"I would rather share one lifetime with you than face all the ages of this world alone"


I know it's long and I know Arwen does not say this line in Elvish in the movie but I would be greatly appreciative if someone can translate it for me!

Thank you!!

"Laumë, e nai cuianyë er quantacuilë aselyë, lá lemya ilyë randar Ambaressë sina erinqua."

It's as literal as I could get it: it means literally "On the contrary, may I indeed live one full-life with you, not remain alone for all the ages of the World" with word order varied.
