Okay kiddo, so a will is something that grown-ups make to say what they want to happen to their things when they are no longer alive. A gnomic will is a fancy word for a type of will that is kind of hard to understand because it doesn't use normal words to say what the grown-up wants to happen to their things. Instead, it uses riddles or sayings that make sense to the grown-up but might be confusing to other people. So, if someone has a gnomic will, it might take a lot of figuring out to understand what they really wanted to happen to their things.
