Boarder and border are both correct words but have different spelling and meanings. Boarder (the one that’s spelled with the letter “a”) is used as a noun that means two things: a student staying in a boarding school or someone renting in another’s house. Meanwhile, border is used as a noun and verb in many ways, but generally, it deals with a boundary or edge of something.
As a noun, a border is the outer part or edge of something or a specific area; an ornamental design at the edge of something; and a boundary dividing different territories. Moreover, border functions as a verb that means to touch at the edge or boundary and to lie on the border.
When to Use Boarder
