What does nomen mean?
Nomen is a formal English noun meaning “name” or “designation,” especially when a person or thing is identified in legal, historical, or classical records. It is much less common than the ordinary word “name,” and its use often conveys a sense of formality or technical precision. The word is particularly familiar from the Latin expression “nomen nescio,” meaning “I do not know the name,” used when the speaker cannot identify someone or something. In Christian and manuscript studies, “nomen sacrum” refers to an abbreviated sacred name. Although nomen is fully established in English, it is chiefly encountered in learned, literary, historical, and legal contexts. Its Latin origin also connects it to familiar words such as nominal, nominate, and nomination, making it useful for understanding the vocabulary of naming and identification.

Etymology of nomen
Nomen comes from Latin, where it means “name” and is the nominative singular of the noun nomen. Latin later developed a plural nomina, which is also the standard plural of the English borrowing. The word entered English through learned and legal usage, and its most recognizable expression, nomen nescio, preserves the Latin phrase meaning “I do not know the name.”
