Eng-->Latin Translation, Please.

In Latin, unus is used as a number, not in the sense you want to use it.
However, if that's what you prefer, I'll do it your way.

> The (ancient) Dark One (Is "obscuritas unum" be acceptable?)
I don't know why you have "ancient" in parentheses.
"obscuritas" means "darkness" and is feminine
"unum" is neuter

I would use
Obscurus or Oscurus Unus if you prefer.
assuming this "Dark One" is masculine

>The (ancient) Dark Soul
Anima Obscura

> The (ancient) Evil One (Is "infernus unum" be acceptable?)
"infernus" means underground, the underworld, or hell.
I would use
Malus or Malus Unus


> Sent from the Dark One.
Missum de Obscuro
-or-
Missum de Obscuro Uno
I am assuming that what is sent is a singular thing.
If it is plural or a person or persons, the ending of Missum would change.

> From out of the Dark One
Ex Obscuro Uno

> One of Many Evils
Unum de Multis Malis

> The Dark Light
Lux Obscura


> Also would the following be correct usage:
> Diabolis Unum --> The One Demon/Evil or The First Demon/Evil
The One Demon is Diabolus Unus
The First Demon is Diabolus Primus

WOW!!

Thank you so much, George.

If I may follow up:
So, I do not want this entity to be considered male or female. Is "Obscurum Unum" acceptable?


One more thing that I am wondering about now. This is probably a silly question.: The motto of the USA is "e pluribus unum". Why isn't it "e pluribus unus" or "e pluribum unum"?

Yep. That would make it neuter in gender.

Not silly at all.

It is not unus, because the "one" in this case is a thing (neuter).

It is not pluribum because there is no such word. Pluribus is the ablative
case (of plus) which is required by the preposition e.

Feel free to follow up as much as you want. I'm enough of a geek to enjoy
talking about this stuff.

Way cool! Thanks. I will take you up on your offer...

So Google translate is telling me this:
"the one below" --> "unum inferius". How'd Google do? Could you also say "inferius unum"?

In general, what is your opinion of Google translate for latin?

Google did well.

The Latin adjective inferus means "below" "beneath".
Inferius is the comparative neuter form (inferior is the comparative masculine
or feminine form, by the way).

Sure could. The usual word order in Latin is noun followed by adjective -- like
French. But word order is less important in Latin and is sometimes turned
around for emphasis.

I think it is the best of the automated translators of Latin that I have seen.
And it's getting better. But there's a long way yet to go.

They have a huge database of Latin literature so sometimes you'll get a
translation that is right on the money.

This was extremely helpful!

Gratias tibi ago!

Any time
