A more thorough explanation:

Definition: Heirdom is the state of being an heir, which means inheriting something from someone who has died. It is the process of succession by inheritance.

Example: When the wealthy businessman passed away, his son inherited his entire estate, including his businesses, properties, and investments. The son then became the heir and took over the heirdom of his father's wealth.

Explanation: This example illustrates heirdom because the son inherited everything from his father after his death. He became the heir and took over the heirdom of his father's wealth, which means he became the new owner of everything his father had owned.
