Updated Tue Jul 04 2023
A collection of (mostly unisex/feminine, since masculine names ending in 'o' can be found in any spanish/italian name list, really) names ending in 'o'. I find that having similar sounds/letters in common throughout the name makes for an interesting alternative to matching the initial in regards to family/sibling themes
  1. Arlo

    • Origin:

      Irish, English

    • Meaning:

      "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".
  2. Bo

      On trend for boys but with plenty of unisex appeal too, the place name Cairo was put on the map for girls when model Beverly Peele chose it for her daughter. Given to around 50 girls each year, it hasn't caught on just yet but with its similar sounds to Kaia and Skyler, it might do in the future.

      Greek

    • Meaning:

      "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.

    • Description:

      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.

      "estate ruler"

    • Description:

      Victoria's Secret model Devon Windsor welcomed a daughter named Enzo Elodie Barbara in 2021. It hasn't yet inspired many parents to use Enzo for their baby girls — there were only 6 in 2022 — but we could see this becoming as unisex as Ezra someday.
  13. Flo

    • Origin:

      Diminutive of Florence, Latin

    • Meaning:

      "flourishing, prosperous"

    • Description:

      Flo is an antiquated nickname not often used these days, possibly because "Aunt Flo" is a euphemism for a period.

      Greek

    • Meaning:

      "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. Although most people don't think of it like this, Indigo might also be considered among the most stylish Greek baby names in use today. Some cultural references: The Indigo Girls are a folk duo, 'Mood Indigo' is a classic Duke Ellington jazz composition, and there is a 1970's New Age theory that Indigo children possess special, sometimes supernatural abilities. 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.

      The name Jo still evokes the spunky image of the character in Louisa May Alcott's Little Women. Its literary status makes Jo one of the OG boyish nicknames for girls, ala Frankie, Billie, and Stevie. If you like that form, you can lengthen it to Joey.
  18. Jojo
