The Puzzle of Shared Possession

The most common first name in the world is Muhammad. Names are personal, yet globally shared.

In many cultures, a person's name is believed to carry power and personality. That's why 'using it more' matters.

Some indigenous tribes believe that if you overuse someone's name, you borrow a part of their soul.

The study of personal names is called anthroponymy. Your name is yours, but others use it to define you socially.
