A more thorough explanation:

Definition: Egress is a word that can be used as both a verb and a noun. As a noun, it refers to the right or ability to exit a property. When talking about easements, egress is often paired with "ingress," which refers to the right to enter a property, and sometimes with "regress," which refers to the right to return to a property from afar. As a verb, egress means to exit or leave.

Noun: The new building plans include an egress that leads directly to the parking lot.

Verb: After the concert, the crowd began to egress from the stadium.

These examples illustrate how egress can be used to describe both the act of leaving a place and the right to do so. In the first example, egress is used as a noun to describe a physical exit that is being built into a new building. In the second example, egress is used as a verb to describe the action of the crowd leaving the stadium after the concert.
