Three Letter Girl Names

In the 21st century, Exa is best known as the given name of Grimes and Elon Musk's daughter Y, a sibling for X Æ A-XII. The celebrity parents were inspired by the supercomputer terms exaFLOPS, which is the "ability for a supercomputer to perform 1 quintillion floating-point operations per second."

Neo, indeed--though it was a male character in "The Matrix."

Sif, or sometimes Siv, was the name of Thor's wife and is popular in modern Scandinavia. In Norse mythology, Sif was the goddess of fertility and agriculture.

There are almost the exact same number of female and male Sidneys born in the US these days, which makes Sid a perfect gender-neutral nickname. And cute for boys or girls.

An unusual nickname for unusual names — Mazikeen, a name invented by Neil Gaiman for his Sandman comics, and Mazarine, a French color name.

One of the few Korean names to migrate to Western culture, via supermodel Hye Park.

Sua is a short and sweet name with many different origins, including Chinese, Korean, Vietnamese, and Basque. It would make a fresh and offbeat honor name for a familial Sue.

Though rarely heard now, Coy has been around for a century and was not an uncommon name for boys a hundred years ago. There have been a couple of NFL players named Coy, Coy Bowles is in the Zac Brown band, and of course there was Coy Duke in The Dukes of Hazzard. Due to the flirty connotations of the word "coy", McCoy is a more popular and recommended choice today.

The meaning of this word flipped from "cheerful" to "homosexual" during the twentieth century, and it's now almost certainly too loaded to sit comfortably as a baby name. Which is a shame as sound-wise it's very appealing, just a short step away from Faye, May, and Rae.

Kin was a popular girl name in Japan during the 18th and 19th centuries, after which it fell out of use.

In English, a fen is a wetland fed by surface and/or groundwater. In Dutch and Frisian, it's a traditional diminutive of names containing the element frid, meaning "peace".

Ro- names are on the rise — think Roman, Rory, and Rowan — but straightforward and streamlined Row (and Rowe, Roe, and Ro) takes this trend to the next level. The pared-down single syllable gives Row an ultra-cool edge.

In keeping with other short names like PO/POE and BO, Coe is a surname that could easily move into first place. It has a sports hero factor as well, in Olympic runner Sebastian Coe--who later became a Member of Parliament.

Very Brady Bunch.
