Prince is a general term for a ruler, monarch or member of a monarch's or former monarch's family, and is a hereditary title in the nobility of some European states. The feminine equivalent is a princess. The English word derives, via the French word prince, from the Latin noun princeps, from primus(first) + capio (to seize), meaning "the chief, most distinguished, ruler, prince".

The Latin word prīnceps (older Latin *prīsmo-kaps, literally "the one who takes the first [place/position]"), became the usual title of the informal leader of the Roman senate some centuries before the transition to empire, the princeps senatus.

Emperor Augustus established the formal position of monarch on the basis of principate, not dominion. He also tasked his grandsons as summer rulers of the city when most of the government were on holiday in the country or attending religious rituals, and, for that task, granted them the title of princeps.

The title has generic and substantive meanings:

The original, but now less common use of the word, originated in the application of the Latin word princeps, from Roman, more precisely Byzantine law, and the classical system of government that was the European feudal society. In this sense, a prince is a ruler of a territory which is sovereign, or quasi-sovereign, i.e., exercising substantial (though not all) prerogatives associated with monarchs of independent nations, as was common, for instance, within the historical boundaries of the Holy Roman Empire. In medieval and Early Modern Europe, there were as many as two hundred such territories, especially in Italy, Germany, and Gaelic Ireland. In this sense, "prince" is used of any and all rulers, regardless of actual title or precise rank. This is the Renaissance use of the term found in Niccolò Machiavelli's famous work, Il Principe.

An enemy or foe is a relativist term for an entity, whether an individual or a group, that is seen as forcefully adverse or threatening. The concept of an enemy has been observed to be "basic for both individuals and communities". The term "enemy" serves the social function of designating a particular entity as a threat, thereby invoking an intense emotional response to that entity. The state of being or having an enemy is enmity.

"Enemy" is a strong word, and "emotions associated with the enemy would include anger, frustration, envy, jealousy, fear, distrust, and possibly grudging respect". As a political concept, an enemy is likely to be met with hate, violence, battle and war. The opposite of an enemy is a friend or ally. Because the term "the enemy" is a bit bellicose and militaristic to use in polite society, informal substitutes are more often used. Often the substituted terms become pejoratives in the context that they are used. In any case, the designation of an "enemy" exists solely to denote the status of a particular group of people as a threat, and to propagate this designation within the local context. Substituted terms for an enemy often go further to meaningfully identify a known group as an enemy, and to pejoratively frame that identification. A government may seek to represent a person or group as a threat to the public good by designating that person or group to be a public enemy.
