the.com/naming ceremony

means A formal event at which a person (often a baby) or sometimes a ship, place, or thing is officially given their name, usually with rituals, witnesses, and a bit of ceremony to make it stick.

from 'Naming' traces back to Old English 'nama,' a word so old it shares ancient roots with Latin 'nomen' — the same root that gives us 'nominate' and 'noun.' 'Ceremony' arrives via Old French 'ceremonie' from Latin 'caerimonia,' meaning sacred rite or religious observance, itself of uncertain deeper origin. The practice of formally naming the newly arrived — child, vessel, or settlement — is ancient and nearly universal, found from religious christenings to secular registry-office declarations, long before the phrase 'naming ceremony' itself became the catch-all term used across cultures and faiths today.
