In law, a person who makes a devise; someone who leaves property to someone else in their will.
From devise with the agent suffix -or (Latin -ator). This is the legal term for the person doing the devising in wills and estates.
Here's the cool legal distinction: a 'devisor' specifically leaves real property (land and buildings) in a will, while a 'testator' leaves everything—it's a specialized legal vocabulary that lasted for centuries.
