A prince (from the Latinprinceps) is a male member of royalty or a royal family. The female form is princess. Although this is the most commonly understood definition, there are also different systems in different countries.
On the European continent, notably in the German system, a prince is something more than a mere noble, but not necessarily royal, which makes comparing it with the British system of royal princes difficult.
In the Russian system, "knyaz" (translated as "prince", e.g., Prince Potemkin) is the highest degree of nobility, and sometimes, represents a mediatization of an older native dynasty which became subject to the Russian imperial dynasty. Rurikid branches used the knyaz title also after they were succeeded by the Romanovs as the Russian imperial dynasty.
In imperial China, the title of prince developed from being the highest title of nobility (synonymous with duke) in the Zhou Dynasty, to five grades of princes (not counting the sons and grandsons of the emperor) by the time of the fall of the Qing Dynasty.
A teritorry over which a prince rules is called principality.
The child of a monarch (king or queen-regnant), and in the direct line of succession also other members of the royal family, styled a "royal highness". The precise rules for the succession are fixed by law. (e.g. a "Prinz" in German.)
A member of the higher nobility in certain countries and periods. Foreign-language titles such as Italianprincipe, GermanFürst, Russian kniaz, etc., are often rendered as prince in English. For example, one can talk about Prince Bismarck (Ger. Fürst B.).
The term has also been used to describe the head of a feudal state; for example, it has been used as a synonym for duke at times.
I'm not expecting Prince to roll out a tour on the scale of those of his Purple Rain days, but considering it's been two decades since the release of Sign 'O' the Times (Paisley Park), a live rendition of the entire album would be quite nice.
Prince's last album 3121 (hence the ticket price tag) was a messy affair; a random sampling of 12 tracks from his unedited unconscious that mixed in every superfluous bell, whistle, clap and string at his disposal.
Prince Rogers Nelson was born in 1959 to John Nelson, a jazz pianist, and his wife Mattie, a backing singer.
Indeed, various princelytitles are derived from the ruler's, such as (e)mirza(da), khanzada, nawabzada, sahibzada, shahzada, sultanzada (all using the Persian patronymic suffix -zada, "son, descendant"; or (maha)rajkumar from (Maha)Raja and Kolano ma-ngofa 'son of the ruler' on Tidore, again patronymic; or even from a unique title, e.g.
Other princes (or the same, see below) derive their title not from their dynastic position as such (which must often be shared with brothers, etc), but from their claim to a unique title of formal princelyrank, one named after a specific principality, not after the suzerain/sovereign state, even if they belong to one.
