Meaning & origin

Primus is a Latin name meaning 'first,' historically given as a name to the firstborn son in some families. Records from the U.S. Social Security data show the name first appearing in 1881, which also happens to be its peak year. In that year the name was given to a few dozen boys. Since then its usage has been sporadic and very low. The name has not appeared consistently enough to calculate a rank or a one-in-N probability. It belongs to a category of names derived from Latin ordinal numbers, similar to Secundus or Tertius. While never widespread in the United States, it has a classical feel that has occasionally appealed to parents looking for a rare and distinctive name with a literal meaning. Its trajectory is stable, meaning it has been used at a very low but consistent level over the decades. No states have recorded enough uses to be listed among its top states, suggesting it is scattered across the country rather than concentrated in any region.

Primus is a Latin adjective meaning 'first' or 'foremost.' In ancient Rome, it was used as a cognomen or given name, particularly as a hereditary name in the gens. The name saw limited use in English-speaking countries, sometimes appearing among early Christian communities and occasionally as a name for the firstborn son.
