Begins or Ends with O

Like Horace, Horatio is a variation on the Latin Horatius, but its Shakespearean and optimistic Horatio Alger pedigree makes it an attractive up-and-comer, especially with its cool final o. A modern reference is the charismatic TV character Horatio Caine played by David Caruso in CSI: Miami.

A multicultural choice with an appealing open O sound, Omar blends stately strength with familiarity. Also transcribed as Umar, it is a popular choice among Muslim families and features in the name charts across the globe.
Long associated with the twelfth-century Persian poet, Omar Khayyam, Omar derives from the Arabic umr meaning "life", though is typically interpreted as meaning "flourishing, thriving" and "long living", making it an aspirational choice. In Islamic tradition, Omar (or Umar) was the second caliph (a religious ruler) and companion of the Prophet Muhammad.

Oslo, the capital city of Norway, makes for an intriguing new place name, especially with its bookended O's, as in Otto and leads to cool nickname Ozzie. One Berry has already used it and we predict others will follow; in fact, stats suggest it is used eight times more often than it was a decade ago.

A lively nickname with the cool -o ending, Lando has been racing up the UK charts following Lando Norris's Formula 1 debut in 2019. Appearing in the Top 1000 for the first time in 2020, a more recent year saw it place in the Top 300 when it was given to five times as many babies.

A biblical place name with trumpeting verve and strength.

Jethro, though the biblical father-in-law of Moses, has suffered for a long time from a Beverly Hillbilly image, but some really adventurous parents might consider updating and urbanizing it and transitioning it into the hip o-ending category.

For centuries this name was associated primarily with the towering figure of Italian Renaissance painter-scientist-inventor Leonardo da Vinci, and was scarcely used outside the Latin culture.

Well used in the Latino and Italian-American communities.

An evocative unisex one-syllable name, Poe is most distinguished by its literary reference. Edgar Allan Poe was an influential American author and poet, credited with inventing the genres of detective and science fiction, which might provide inspiration for parents who are fans. And now its choice as the name of the hero played by Oscar Isaac in the new Star Wars movie is sure to catapult it from literary choice to major favorite.

Words are not always easy to translate into baby names, but the implications of being straight and swift lend this one great potential as a name. It also has the popular o-sound ending, which brings it further into the realm of possibility. Rising rock star Aja Volkman pulled a gender switch when she named her daughter Arrow Eve.

A vibrant, operatic choice with plenty of flair and plenty of familiarity too. Popular in Italy, Chile, Uruguay, and Brazil, it also ranks in the Top 500 in France and the US. Operatic tenor Luciano Pavarotti and football manager Luciano Spalletti are two notable bearers

Benno is a cool name in its own right -- there was a tenth century Saint Benno -- though it is also used as a lively nickname for Benjamin. Saint Benno of Meissen is the patron saint of anglers and weavers and, strangely enough, alliteration.

Joe is still the ultimate good-guy name, not at all diminished by its longevity or popularity or its everyman rep as Regular Joe, Cowboy Joe, G.I. Joe, Joe Exotic, Joe Blow, Joe Millionaire, Average Joe — and now President Joe (Biden).

Oskar is to Oscar as Jakob is to Jacob: more distinctive and continental.

Old Testament name of a king of Israel, related to the harvest.

Calixto is known in Spain as the name of three popes, one of whom was the martyr, Callixtus I, regarded as a saint.
