Begins or Ends with O

Osian is the easier-to-comprehend version of the ancient Irish Oisin, an important name in mythology. Osian or Oisin was a warrior poet. Osian is popular in modern Wales and England. While Oisin is pronounce oh-SHEEN, Osian is pronounced o-SHAN -- though we bet most Americans would just say ocean, which you may consider a good thing.

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

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.

Ossie is best-known as the name of actor Ossie Davis, whose full name did not start with Os: It was Raiford. But Ossie makes a cute contemporary short form for any name beginning with Os.

Otto is cool again. Long a quintessential Old Man Name, Otto has been promoted to trending darling of adventurous baby namers.

Ovid is the English form of the Roman family name Ovidius, which possibly comes from the word for sheep. It is the usual English name for the first-century poet Publius Ovidius Naso.

Owain is much more unusual than its brother name Owen, and feels a little more rugged, a little more adventurous and ancient.

Owen, a resonant Celtic name, has ranked among the Top 100 boys' names in the US for 20 years and is now at its highest point ever.

Ozzy has been on the rise in recent years and currently sits in the Top 1000 in the UK and the US. The Ozzie spelling has yet to catch up, but has nevertheless gained more attention thanks to its popular counterpart. Given to 135 boys and to 50 girls in 2023, for every one Ozzie there are three Ozzys.

Cute but cool, fresh but familiar, Ozzy was one of the fastest-rising boy names of 2021 and has continued to rise in the US and the UK ever since. While hard-core rocker Ozzy Osbourne might not be everyone's idea of a role model, his nickname name, along with others like it (think Iggy, Ziggy and Izzy) are forging their own way up the charts.

Pablo, the commonly used Spanish version of Paul, has the added bonus of some fantastic artistic bearers: painter Picasso, cellist Casals, and poet Neruda. Pablo has been consistently in the US charts since records began, and has been within the Top 500 since the mid 60s. However, Pablo has never cracked the Top 200, making it familiar but not overused or tired.

Paolo is an irresistibly lush Italian name for boys, worlds more romantic than its spare English equivalent.

Paulo suffers in comparison to the richer and more authentic-sounding Paolo.

The name of one of the greatest Western philosophers is often used as a first name in its land of origin, Greece, and would make a really interesting, thought-provoking choice here. It is remembered here as the nickname of the memorable character played by Sal Mineo in the classic film "Rebel Without a Cause."
