A more thorough explanation:

Definition: Gratification is an old-fashioned word that means a reward or payment given voluntarily for a service or benefit. It can also refer to the feeling of satisfaction or pleasure that comes from achieving something or receiving a reward.

Example 1: In the past, it was common to give a gratification to someone who provided good service, such as a waiter or a delivery person. This was a way of showing appreciation and encouraging them to continue doing a good job.

Example 2: When you work hard and achieve a goal, you may feel a sense of gratification. This is the feeling of satisfaction and pride that comes from knowing you did your best and accomplished something meaningful.

Both examples illustrate the definition of gratification by showing how it can refer to a reward or payment given for a service, as well as the feeling of satisfaction that comes from achieving something.
