Begins or Ends with O

  1. Odin
    • Origin:

      Variation of Óðinn, Old Norse
    • Meaning:

      "god of frenzy; poetic fury"
    • Description:

      Odin is the name of the supreme Norse god of art, culture, wisdom, and law — who was handsome, charming, and eloquent into the bargain. The name projects a good measure of strength and power and has excellent assimilation potential.
  2. Orson
    • Origin:

      Latin and English
    • Meaning:

      "bear cub"
    • Description:

      In the past, Orson has felt like a one-person moniker, tied to film director Orson Welles, who dropped his given name of George in favor of his more distinctive middle. While the Citizen Kane creator seemed to own the name during his lifetime, it's now an interesting possibility for any parent seeking an unusual yet solid name. It's started to appear to the celeb set too -- both Paz Vega and Lauren Ambrose have little Orsons.
  3. Oakley
    • Origin:

      English
    • Meaning:

      "oak wood or clearing"

      Scandinavian
    • Meaning:

      "war"

It now feels much more mainstream than many celebrity baby names, sharing the quirky appeal of some other so-far-out-they're-in baby names as Bruno and Hugo.
  6. Bruno
    • Origin:

      Germanic
    • Meaning:

      "brown"
    • Description:

  7. Winslow

      English
    • Meaning:

      "friend's hill"
    • Description:

      Winston meets Marlow in this surname-style choice, blending old-fashioned charm and a hint of stuffiness with a bit of modern edge and breeziness too.

    • Origin:

      Latin
    • Meaning:

      "all-knowing"

    • Origin:

      Spanish and Italian variation of Anthony
    • Meaning:

      "from Antium"
    • Description:

      Antonio is a Shakespearean favorite -- the Bard used it in no less than five of his plays, and has long been a ubiquitous classic in Spanish-speaking countries, where the nickname Tonio is also prevalent. Antonio is also among an elite group of perennially popular names in the US, where it has always been among the boys' Top 1000 since baby name record-keeping started in 1880.
  11. Oberon
    • Origin:

      Variation of Auberon
    • Meaning:

      "elf king; noble bear"

  14. Indigo
    • Origin:

      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.
  15. Aurelio

    • Meaning:

      "the golden one"

      Italian
    • Meaning:

      "pilgrim to Rome, Roman"
    • Description:

  17. Marlow

      English
    • Meaning:

      "driftwood"

      Italian variation of Roland
    • Meaning:

      "famous throughout the land"
    • Description:

      Orlando, the ornate Italianate twist on the dated Roland, with a literary heritage stretching back to Shakespeare and before, has appealing book-ended o's, and is open to combination with almost any last name, a la British actor, Orlando Bloom.

    • Origin:

      Slavic
    • Meaning:

      "peace, world"
    • Description:
