Nameberry's Favorite Three Letter Names

Lou is usually a short form of Louise, Louisa, or Lucy in English-speaking countries, when Lou is used for girls at all. But in France and Germany, it's a fashionable choice all on its own, sure to gain even more widespread style credibility since Heidi Klum and Seal chose it for their daughter.

May is a sweet old-fashioned name that hasn't been on the national charts in several decades, but is definitely sounding fresh and springlike. Parents are beginning to see it once more as one of the prettiest middle name options. May was as high on the list as Number 57 in the 1880s; it's now 228 on Nameberry.

This name of a character played by Kirsten Dunst in the movie Virgin Suicides, originally a novel by Jeffrey Eugenides, is gaining attention, also thanks to the heroine Lux, Lady of Luminosity in the League of Legends games. Luz is the Spanish version.

Pax, one of the variations of names meaning peace that are newly popular in these less-than-peaceful times, got a lot of publicity when chosen by Brad & Angelina for their Vietnamese-born son. Parents attracted to Pax may also want to consider Paz, the unisex Spanish version, or Paxton, a growing-in-popularity surname choice that shares that magical X-factor.

Sky is an ambigender nature name that was first legitimized as the character of Sky Masterson in the 1950 musical Guys and Dolls, played in the film version by Marlon Brando. It's a name we appreciate for its clear, wide-open feel, less hippyish than others like Rainbow and Starlight, and makes an appealing middle name possibility.

Soft name in the Mia-Nia-Tia family, Pia is heard in both European and Hindi languages.

Friendly but substantial.

Isa is a name unto itself as both a Persian name meaning "strong-willed" and as Germanic one derived from the element is meaning "ice". It can also be a short form of Isabel, Isabella, Isadora, Louisa, and similar. Currently popular in Brazil and The Netherlands, it has seen some increased use in the US in recent years, perhaps owing to the popularity of other short names like Ava, Mia, and Isla.

This short but strong name, commonly heard in Israel, has a lot of crossover potential, and is among the most usable on the minuscule menu of U names.

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.

Extremely popular in Wales, where it began as a nickname for someone with fair hair or a fair face, this bright and simple name is a winner by its very nature. Can also be spelled Wynn, Winn or the very literal Win.

This super-charged variation of Jett is on the rise -- along with the unlikely newcomer Jetson.

Ned is a gently old-fashioned Nancy Drew-Bobbsey Twins-era short form for Edward that sounds cooler than Ed and is enjoying a small style renaissance.

Mia, Gia, and now Sia!

Ike, once the quirky one-person nickname of President Dwight Eisenhower, has morphed into a cool kid nickname of the early 21st century.

Oak, a symbol of solidity, strength, and longevity, is joining Cedar and Pine as a viable name, one that would work especially well in the middle.

Cool short form of Alexander, fresher than Alex and less trendy than Xander... for now.

The name of Rip Van Winkle – and Rip (born Elmore) Torn – will probably never be ready for further consumption, if only because of the implications of R. I. P. The only thing that could save it is Rip Wheeler, the handsome ranch foreman on the soapy Western Yellowstone.

Though short and brisk, no nickname name could have a more creative image. Comic actor Chris O'Dowd named his son Art, as in his native Ireland it's used as a name on its own, separate from Arthur., coming from an ancient word for ""a bear,"" and used in the sense of ""outstanding warrior"" or ""champion."" A pagan High King of Ireland, Art’s rule was so honest that two angels hovered over him in battle.

This attractive mini-name combines multiple trends: the R initial, vowel-ending boy names, and a fantastical meaning.
