I linked to that Wikipedia article because it's filled with important information about the subject that we're discussing. I get the impression that you didn't read it or that you read it but didn't understand it.
But if you feel that that's not enough, then here's a link to a (small) Latin-Sardinian dictionary that you can read for free on the internet:
You can compare the two languages to each other and observe all the similarities. Of course, it helps if you also speak Italian because then it will become apparent why Sardinian is considered the most conservative Romance language (and thus the closest to Latin).
