Alex functions as a short form of Alexander or Alexandra, inheriting the Greek sense of "defender" while shedding some of the longer name's formality. Its brevity and unisex use have made it read as adaptable -- a name that moves easily between contexts rather than announcing a fixed identity.
Destiny is not a matter of chance, it is a matter of choice; it is not a thing to be waited for, it is a thing to be achieved. (Bryan, William Jennings, 1860-1925, American Lawyer Politician)
