A more thorough explanation:

Suum cuique tribuere is a Latin phrase that means to give each person what they deserve.

• When you work hard and do a good job, your boss should pay you a fair wage. This is an example of suum cuique tribuere.
• If someone helps you out, it's important to thank them and return the favor. This is another example of suum cuique tribuere.

These examples illustrate the idea that everyone should be treated fairly and given what they deserve. Whether it's a fair wage for a job well done or gratitude for a kind act, it's important to give each person their due.
