Etymology of spanish words

[Muammar]

Is there a proper place on the internet where I can find spanish etymology with english explanations?

I've been putting connections together, but I can't seem to find whether or not I'm correct with my assumptions about particular words. Like the word "adiós", does it come from a root of "a Dios"(To god)? Or is this just a coincidence that I've located?

Help is appreciated.

You can find word origin via RAE (Royal Spanish Academy) Tomísimos dictionary has a link to it if ever you want to delve more deeply into word meanings and etymology.

Yes, Muammar. "Adiós" comes from "A Dios"...

As poli notes already, you can find it in DRAE

Good luck!

I use http://www.myetymology.com a lot. When I'm trying to think of ways to memorize a new word, it's often helpful to take a look at the etymology.
