Quarto

Quarto is a name directly derived from the Latin word 'quartus', meaning 'fourth'. Historically, names derived from numbers were often given to children based on their birth order, particularly in Roman culture. For example, a fourth-born son might be named Quarto. While not a common given name in modern times, its roots are firmly in this ancient practice of numerical naming.

In some contexts, 'quarto' also refers to a specific size of book or paper, derived from the practice of folding a sheet of paper twice to create four leaves. This usage, however, is distinct from its application as a personal name, though both share the same Latin etymological root.
