Soulless Words

Words are everything, from the way we interact to the way we remember history. Words are simple, yet complex, but carry more emotion than anything else in the world. Why? Because everyone has the ability to use words to their advantage, and in some cases, to their demise. Now, imagine a world where words not only do that, but they grant you super human abilities. When someone is born, a word will activate a ability that allows them to summon unknown powers. Such as "Strength" granting immeasurable strength, "Flight" allowing you to fly, "Dog" allowing you to summon a dog. Now, imagine if the words granted to a person determined everything. Their status in life decided by birth. What then?
