Origin & Etymology of Neptune
Latin · Latin
Neptune comes from Latin, where it means '(the god of the sea)'. When families carried the Latin tradition abroad, Neptune went too, picking up minor spelling shifts without losing '(the god of the sea)'.
Neptune holds a meaningful place in the Latin tradition, its sense of depth, freedom and the ocean's calm tied to long-standing cultural values.
How Latin names are chosen
Rome gave a child its given name at the dies lustricus, a purification held on the eighth day for a girl and the ninth for a boy. The delay was deliberate: until the umbilical stump fell away the infant was not regarded as having a separate existence, and so had no claim on a name or a fate of its own. The ceremony washed the child, presented it at the lararium before the household gods, and ended in a family feast. The praenomen given that day was only the first of the tria nomina — praenomen, nomen, cognomen — the three-part structure that marks Roman naming out from almost everything around it.
