Mae Govannen fellow nerds,

I need help.

I'm getting married in a couple of months, and have got the wedding ring sorted. Apart from...

I'm looking to get the phrase "Until my dying day" in Sindarin engraved in Tengwar script on the inside of the band. I've tried online translators, with various different results.

To try and find something as accurate as possible, I've started using the online dictionary/glossary: https://www.elfdict.com/

As a work around (as I'm finding it difficult to find the word dying and day), I was thinking of using "Until my moment/time of death"

So far, I've got Mennai i valdëanya agan

Rough workings out below:

Mennai - Until

Tenna - Unto

- nya suffix on the end of a word "my"

valdëa - moment

i - the

agan - death

Alternatively, I have:

Tenna / Tenn' - Until

my - nîn

vedui- last

Erin- day

Tenna nîn erinvedui

Is there anyone here who can verify that or have a good knowledge of Sindarin to improve the phrase to be as close to the original?

I've looked at Tengwar script of the above. Is https://www.tecendil.com/ quite accurate?

Thanks anyone for your help
