Nebmaatre (prince)
Nebmaatre, as a title, is most commonly associated with pharaoh Amenhotep III of the Eighteenth Dynasty of Egypt's New Kingdom. While "Nebmaatre" translates to "The Lord of Truth is Ra," or "Ra is the Lord of Truth," and served as his prenomen (throne name), it is important to distinguish between Nebmaatre as a royal name and Nebmaatre used as a title or epithet for a prince.
As a general title, "Nebmaatre" is not standardly used to designate the position of "prince" in ancient Egypt. Princes were typically designated with titles such as "sa-Ra" ("son of Ra"), "irj-pat" (a high-ranking noble title often given to royal family members), or were specifically identified with their father's name and the title "son of" or "daughter of."
Therefore, when encountering the term "Nebmaatre (prince)," it is likely a reference to a prince who lived during the reign of Amenhotep III and was possibly associated with aspects of his cult or administration, or it may indicate an attempt to link a prince's identity or name in some way with the royal ideology embodied by the pharaoh's prenomen. Further contextual information would be needed to ascertain the exact nature of the connection. Without further evidence, it cannot be definitively stated that "Nebmaatre" served as a formal title exclusively designating princely status.
