What's Cia short for? Cynthia or most any other C-name. Stylish in its sleek Mia-Nia minimalist feel, but may remind some of the Central Intelligence Agency.

Tim is a boyish short form occasionally given on its own. There were 37 baby boys named Tim in the US last year, versus over 1700 named Timothy.

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 evocative short name is suddenly chic — it was recently chosen by Jennifer Lawrence for her baby boy. JLaw's son's name honors Cy Twombly, the influential mid-century American artist. Born Edwin Parker Twombly Jr., both Cy Twombly and his father shared a nickname after baseball player Cy Young (himself born Denton True Young).

Jen is a short, crisp feminine name that originated primarily as a diminutive of Jennifer, though it can also be a nickname for names like Jenna, Jenny, or Genevieve. The root name Jennifer comes from the Welsh 'Gwenhwyfar,' meaning 'white wave' or 'fair spirit.' Jen gained independent usage during the 1970s and 1980s when Jennifer was at peak popularity, with some parents choosing to put just 'Jen' on the birth certificate. Its simplicity and directness appeal to those preferring unpretentious, straightforward names. While Jen's popularity as a stand-alone name has declined since the 1990s, it maintains appeal for its brevity and friendly, approachable quality. The name carries a casual confidence and remains recognizable without being overly common as a formal name.

Uma is a sweet, strong name for a Hindu goddess... and a Hollywood one. But as popular as Uma Thurman is, other parents have not yet picked up on her name, making it a rarity.

As Tyler has begun to recede, a number of parents, including the Wayne Gretzkys, have cut straight to the livelier short form.

Fay, also spelled Faye, who had been napping quietly since the 1930's, has, like cousins May/Mae and Ray/Rae, sat up and started rubbing her eyes, ready for a mini-comeback, especially as a middle name. In 2014, Faye hopped back onto the US Top 1000, though Fay is used much more quietly as a first name.

This is one of the ninety-nine attributes of Allah, deemed by Muhammad to be a recommended name for a male child. In this country, it's been primarily associated with boxing immortal Muhammad Ali, known as "the greatest." But Ali is also one of the most popular unisex names for both boys and girls.

Some might think a girl named Liz on her birth certificate would feel deprived of her full identity, but in a time when mini names like Liv, Kit, Tru, Kai, Lou, and Bea are in style, Liz feels substantial enough that its bearer won't feel bereft.

Io may be one of the slightest names in the book, but there aren't many two-letter names with as much substance as this Greek mythological example. Io, a name used for the largest moon of Jupiter, was in classic myth raped by Zeus and escaped from him by changing herself into a cow.

The Old Testament Noah has been so popular for so long that variations are becoming popular too. Noe is a streamlined form used in Greek and Latin Bibles, and in Georgia too. Spelled as more often as Noé, it is also popular across France, Belgium, Switzerland, and Spain.

Sky may be a bit hippie-ish, but it's bright and sunny nonetheless. Sky rejoined the Top 1000 in 2013 after spending many years off the list. Sky was the choice of magician David Copperfield for his daughter, born in 2010.

Short but spirited, Pim is in the Top 200 in The Netherlands, though it is little-known elsewhere. A diminutive of Willem (or William), it possibly emerged via its rhyme with alternative, more direct short form, Wim.

Kay, a cigarette-smoking, nightclubbing name of the 1930's, could be ready for a comeback along with cousins May/Mae and Ray/Rae.

If Gus and Max have made it, why not Moe? Can it be the lingering Three Stooges effect? We think that Moe, like Joe, is one of the friendliest and most open of regular guy nickname names and should get a little more attention.

We're hearing Kat more and more being used by Katherines who are tired of Kathy, Kate and Katie. Katti or Kattie is another possibility.

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

A spiritual word name used by actor Zoe Saldana for her son as well as more recently Nick Cannon and Alyssa Scott for their late son. Zen has been trending in recent years along with other spiritual names such as Bodhi and Zion, and recently entered the US Top 1000 for the first time in 2022.

Kids love Bob the Builder, but do they want to be Bob the Builder? Bob and Bobby have been out of style since the 1960s, but as vintage nickname-names -- Fred, Archie -- come back into vogue, Bob may tag along. Charlie Sheen used it for one of his twin sons.
