A prince is royalty, the son of a king or queen. Originally, a prince was the ruler of and individual territory, also known as “principalities.” A prince is a popular fairy tale hero, but there are real live ones, too.

A prince is the son of a monarch, possibly even the person who stands to inherit the title of king after his father's death. Sometimes, though, a prince is simply a member of the royal family, or even a ruler over a small area of the monarch's country. Prince comes from the Latin princeps, "first man" or "ruler," from primus, "first." A prince is often first in line to inherit the throne.
