Repudiate, Substantiation

Repudiate- to refuse to accept something as true; to refuse to support something

Ex: He repudiated his son’s marriage, for this bond served to break the generations-spanning tradition of keeping the family consisting entirely of stonemasons. “Dad, this is ridiculous! How many stonemason women are there out there? Actually, better yet, how many fucking stonemasons are there in the modern world, regardless of gender!? You were extremely lucky to have found mom, you know that? How often are you going to run into an attractive woman whose village in Italy was buried under heavy stones from a landslide, and she had no choice but to carve her way out, imbuing her with a passion for stonemasonry? Newsflash, dad, not very often!”

Substantiation- proof of something

Ex: The Pawn Stars guys weren’t buying that she really had a fully functional medieval toilet from the Château de Castelnaud. “Yea, we’re going to need some substantiation before we make you an offer.” In order to verify her relic, they dialed up their 13^th century toilet guy. No matter how obscure the antique, they always had a massive loser who they could ring up for advice before deciding to make a bid.
