A more thorough explanation:

Definition: Availment is the act of using or taking advantage of something for oneself.

Example: The availment of the benefits of a gym membership can help improve one's physical health.

Another example: The availment of a scholarship can help a student pay for their education.

These examples illustrate how someone can take advantage of something for their own benefit. In the first example, someone can use their gym membership to improve their physical health. In the second example, a student can use a scholarship to pay for their education and improve their future opportunities.
