Grand Prince

Grand prince or great prince (feminine: grand princess or great princess) is a hereditary title, used either by certain monarchs or by members of certain monarchs' families.

Grand duke is the usual and established, though not literal, translation of these terms in English and the Romance languages, which do not normally use separate words for a "prince" who reigns as a monarch (e.g., Albert II, Prince of Monaco) and a "prince" who does not reign, but belongs to a monarch's family (e.g., Prince George of Wales). Some Slavic and Germanic languages do use separate words to express this concept, and in those languages, grand prince is understood as a distinct title (for a cadet of a dynasty) from grand duke (hereditary ruler ranking below a king). Some recent sources also use archduke.
