Where it comes from

The story of Carlus

Charles entered written Latin as Carolus, the form behind the adjective Carolingian and the Latin name of every King Charles. Carlus is not that form but a two-syllable spelling that sits between Carl and Carlos, found on American records mostly for boys and, much more rarely, for girls. For the girls the record gives no separate source; the same letters simply appear on both registers.

Meaning

free man (through Charles)

Carlus belongs to Charles, from the Germanic karl, a free man, whichever route it took.

Carlus sits in the rare tail. Its best year on record was 1970, with 20 boys. Today it is given to few enough children that it does not enter the ranked charts at all.

Is it right for you

Fashion outlook

Carlus sits outside the current charts, and that is its own kind of answer: naming cycles can only date the names they carried up. A name this rare has no decade stamped on it — it cannot go out of fashion, because it was never in.

The trade-off

Practical strengths
  • A clear place in the Charles family, with a meaning that is not in doubt.
  • Two syllables, easy to say and to spell once heard.
  • Carl is available as a short form.
What to consider
  • Nearly every Carlus on record is a boy; a girl given this spelling will be read as a boy on paper, and the -us ending strengthens that impression.
  • Expect it to be corrected to Carlos, or to Carolus by anyone who knows Latin; a quick spelling at each new form settles it.
