1900+ Four Letter Boy Names

Omar has a perfect mix of unusuality and familiarity, with the added plus of a strong, open initial O. Commonly used among Muslim families, Omar was long associated with twelfth-century Persian poet Omar Khayyam, though it sounds anything but ancient now.

More recent well-known bearers have been World War II General Omar Bradley and actors Omar Sharif(born Michael) and Omar Epps.

When Jade first took off as a given name back in the 1970's, it was in fact considered unisex. It ranked in the US Top 1000 first for boys, then for girls, 7 years later. By the 80's however, Jade was more familiar as a girls' name and by the 2000's, it was gone from the charts for boys.

Like many short forms now popular as full names in the Netherlands, Coen—also spelled Koen—originated as the diminutive of the more old-fashioned Coenraad, the Dutch Conrad. May be confused in the US with Cohen, which stems from the Jewish surname designating a priest.

Rook is a choose-your-own-adventure type of name. It has so many meanings and associations, that you have the freedom of choice to decide what resonates with you.

Clay is a rich, earthy one-syllable name with a southern-inflected handsome-rogue image, featured on soap operas and reality TV. Its longer forms are Clayton and Clayborne.

The association with the infamous Nero, the fiddling Roman emperor, would be unavoidable. But there was also the detective Nero Wolfe, hero of many mystery stories.

This nickname for popular and traditional Joseph has a long history of being used as a given name all on its own. Nonetheless, everyone will always assume that Joey is short for the longer form. It might be nice for a potential son to have the option of a more professional and classic name to fall back on.

Rami has gained notoriety in the English-speaking world as the first name of the Oscar-nominated actor Rami Malek, whose parents immigrated to the US from Egypt. Rami also feels more approachable thanks to the stylish Remi, Romy, and Rumi. The only challenge is keeping the pronunciation on track.

This name of an old Hollywood nightclub still retains a spark of glamour.

Jewish parents in particular may be drawn to this quiet, composed name of the first king of Israel and the name of Saint Paul before his conversion. In modern times, it has been associated with Nobel Prize-winning novelist Saul Bellow. Its meaning makes it appropriate for a long-awaited child.

Saul is a character in a John Dryden poem, and heard in the Handel oratorio, "Saul."

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.

Originally a nickname for a third-generation son, as in Thurman Thackeray III, Trey is now being given to others, and it has also expanded to Treynor and Treyton.

Kiro is a rare bird: one of the unique baby names with the stylish o ending. A Macedonian name with the same root as the English name Cyril; we think it is by far the spunkier option. Reminiscent of more popular names like Arlo and Remy, Kiro is a name which wins on three fronts: it has a great meaning, is easy to pronounce, and yet guaranteed to be unique (only 21 baby boys were named Kiro in the US last year).

This once unique and multi-layered word name was used by R&B singer Nivea for her daughter back in 2005, and later, by country musician Jason Aldean. No longer an exclusively celebrity choice Navy is now in the US Top 500 for girls and is on the rise in the UK too. As a boys name, however, it remains an unexpected possibility.

Noam is an underused modern Hebrew name with any number of attractive attributes attached to its meaning; it doesn't have the biblical weight of Noah, but could make a more distinctive alternative to that popular choice. Noam is a Top 10 boys' name in Israel.

Like Friends, Ross is off the air and into syndication as a baby name, having plummeted from its zenith in the late 80s to fall off the US Top 1000 in 2013. Today, Ross is more likely to be a dad name than a newborn name.

One of the most enduring French names, this form of John has been borne by philosophers (Rousseau and Sartre), artists (Millet, Arp) and fashion designers (Gaultier) alike. Often used in a double name with the likes of Pierre, Paul, and Luc, it is a classic in its native country,
