RELATED:
- Cleo
Origin:
GreekMeaning:
"glory"Description:
Cleo, one of the few girls' names to boast the cool-yet-lively o ending, is of course short for Cleopatra, the name of one of the most powerful women in history.
- Juno
Origin:
LatinMeaning:
"queen of the heavens; young"Description:
Juno is an ancient name that feels as fresh as if it had been minted, well, not yesterday, but in 2007. Since the release of the popular indie film Juno, this lively but strong Roman goddess name has held new potential as a baby name. Currently in the UK Top 500 and used in The Netherlands too, Juno is on the rise in the US - and is 15 times more popular than it was before the release of the film.
- Calypso
Origin:
GreekMeaning:
"she who hides"Description:
This hyper-rhythmic name has two evocative references. In Greek mythology, she was an island nymph, a daughter of Atlas, who delayed Odysseus from returning home. It is also a genre of West Indian music, originating in Trinidad and Tobago and largely popularized in the States by Harry Belafonte.
- Indigo
Origin:
GreekMeaning:
"Indian dye"Description:
Indigo is one of the most appealing and evocative of the new generation of color names. Color names have joined flower and jewel names -- in a big way -- and Indigo, a deep blue-purple dye from plants native to India, is particularly striking for both girls and boys. Indigo is the name of a character in the Ntozake Shange novel Sassafrass, Cypress & Indigo, and was used for his daughter by Lou Diamond Phillips.
- Echo
Origin:
Greek mythology nameMeaning:
"echo or sound"Description:
Echo, the pretty, resonant name of a legendary nymph, was the heroine of Joss Whedon's sci-fi series Dollhouse. Nick Hexum, of the band 311, named his daughter Echo Love.
- Rio
Origin:
JapaneseMeaning:
"place of the cherry blossoms"Description:
Rio is one of Japan's most popular girls names, constantly sitting in that country's Top 10. Of course, Rio may also stem from the Portuguese and Spanish word for river, and the Brazilian city Rio de Janeiro. A truly international name for a cosmopolitan baby!
- Coco
Origin:
Spanish and French pet nameDescription:
Coco came to prominence as the nickname of the legendary French designer Chanel (born Gabrielle) and has lately become a starbaby favorite, initially chosen by Courteney Cox for her daughter Coco Riley in 2004. At first it was the kind of name that the press loves to ridicule, but we predict Coco's heading for more broad acceptance and even popularity.
- Margo
Origin:
French, diminutive of MargaretMeaning:
"pearl"Description:
Margo and Margot sound exactly the same, so why has the Margot spelling hopped back onto the Top 1000, outpacing Margo in numbers more than two to one? (Over 350 baby girls were named Margot in the most recent year, versus 150 named Margo.)
- Arlo
Origin:
Irish, EnglishMeaning:
"between two hills"Description:
Arlo, an unexpectedly popular name for boys these days, is also finding new life as a girls' name. The first name Arlo may be rooted in the surname Arlow or the place name Aherlow, meaning "between two highlands". As a surname, it also has roots in a place name meaning "rocky hill".
- Aiko
Origin:
JapaneseMeaning:
"beloved child"Description:
Aiko is a very common Japanese name with a lovely meaning that is rarely heard outside the Asian community.

Origin:
Greek mythology nameDescription:
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.
- Leo
Origin:
LatinMeaning:
"lion"Description:
Leo is of course a very popular name for boys and an equally rare one for girls. But32 baby girls were named Leo in the US last year, and as feminine leonine names such as Leonora and Leonia find more widespread popularity, Leo is popping up as an adorable short form for girls as well as boys.
- Clio
Origin:
GreekMeaning:
"glory"Description:
Clio is the name of the ancient Greek mythological muse of history and heroic poetry, one that is rich with modern charm and would make an intriguing choice, especially thanks to its dynamic o-ending.

Best known as one of the moons of Jupiter, Callisto was a nymph coveted by Zeus who was turned into a bear by Hera, becoming the Great Bear (Ursa Major) constellation.

Norse nickname ; "to live"Meaning:

This tiny but punchy name has multiple origins. It stands strong alone, but could be short for numerous names including Bonnie and Bodhi. In Mandarin Chinese, Bo means "wave".
- Hero
Origin:
GreekMeaning:
"demi-god"Description:
Despite the possibility of gender confusion, the Hero in Greek myth was a woman. Myleene Klass got that when she chose Hero for her daughter, and Sam Taylor-Wood and Aaron Johnson used it as their daughter's middle--and we wouldn't be surprised to see more girls with this heroic name.
- Halo

English, word nameDescription:
Halo is a glowing word name that's both cosmic and spiritual, and with its shiny imagery and bright sounds, it was one of the fasted rising names in 2023.
