A more thorough explanation:

Aboutissement (a-boo-tees-mahn), n. [Law French] An abuttal or abutment.

Aboutissement is a legal term that refers to the point where two pieces of land meet or join together. It is commonly used in property law to describe the boundary between two properties.

Example 1: The surveyor marked the aboutissement of the property line with a stake.

Example 2: The dispute between the neighbors was resolved when they agreed on the aboutissement of their properties.

These examples illustrate how aboutissement is used to describe the point where two properties meet. In example 1, the surveyor marks the aboutissement with a stake to clearly indicate where the boundary is. In example 2, the neighbors were able to resolve their dispute by agreeing on the aboutissement of their properties.
