A more thorough explanation:

Definition: Perdurable (pər-doo-ruh-buhl) is an adjective used to describe an estate in land that is long-lasting, enduring, durable, and permanent.

• The castle was built to be perdurable, with thick stone walls and sturdy foundations that have lasted for centuries.
• The family's wealth was based on their ownership of a perdurable estate that had been passed down through generations.
• The government invested in perdurable infrastructure projects, such as bridges and highways, that would benefit future generations.

These examples illustrate how perdurable refers to something that is built or established to last a long time. The castle, estate, and infrastructure projects are all designed to withstand the test of time and remain in place for many years. Perdurable implies a sense of permanence and stability, which is important when it comes to land ownership and public works projects.
