A more thorough explanation:

Definition: Entirety refers to the whole of something, rather than just a part of it. It can also refer to certain legal judgments and contracts that cannot be divided into parts.

Example 1: The entirety of the cake was eaten by the party guests.

Example 2: The couple owned their house in entirety, meaning they both had equal ownership and neither could sell their share without the other's consent.

Example 3: The court ruled that the contract was binding in its entirety, and could not be divided or altered.

These examples illustrate how entirety refers to the whole of something, whether it be a physical object like a cake or a legal agreement like a contract. In example 2, the term is used in a legal context to describe the ownership of a property, indicating that both parties have equal rights to the entire property. In example 3, the term is used to describe a legal ruling that the contract must be upheld in its entirety, meaning that none of its terms can be changed or removed.
