orgin of some spanish words cognates?

Question

Im looking for a website that gives orgin of cognates

Anversario
religiouso

hehe mispelled its origin

Answer 1

religioso comes from "religión" , which comes from the Latin "religio" = faithful to duty.

Aniversario comes from the Latin "anniversarĭus" = it repeats each year"

I've found a couple of sites about cognates, but I am afraid they are all in spanish.

Answer 2

I don't know a website, but adversario and religioso are Latin cognates.
