A more thorough explanation:

Definition: An abutter is the owner of land that is adjacent to or borders another person's property.

Example: If John owns a house and his neighbor, Sarah, owns a house that shares a property line with John's house, then Sarah is considered an abutter to John's property.

Explanation: The example illustrates the definition of an abutter by showing how Sarah's property is adjacent to John's property. As the owner of the adjoining land, Sarah is considered an abutter to John's property.
