    • Description:

      With a touch of celestial power, a hint of clunky charm, and the totally cool -o ending, Cosmo may well be finally shaking itself free of both the Seinfeld association (which made it a punchline of a joke) and the cartoon fairy association from The Fairly OddParents. In fact, it is in the Top 1000 in the UK and a favorite on Nameberry.
  2. Kai

      Hawaiian, Frisian, Chinese
    • Meaning:

After miracles were reported on the island, the cave was excavated and Sunniva's intact body was found. Sunniva is the patron saint of Western Norway. Her name would make a fascinating and unusual choice for a modern baby girl, and if her story is a bit grim, you can take refuge in the upbeat nickname Sunny or Sunni.

      Roman mythology
    • Meaning:

      "god of war; male; red planet"
    • Description:

  8. Twyla

      English
    • Meaning:

      "woven with a double thread; twilight; star"
    • Description:

      Mystical and intriguing, this vintage name has an unexpectedly modern feel. Conjuring up imagery of glowing evening light, Twyla could appeal as as alternative to Lila, as a nature-inspired option, or for the grown-up fans of the Stephanie Meyer's vampire series, Twilight.

      Twyla — also spelled Twila — has a number of possible origins. On one hand, it could be simply inspired by the word "twilight", connecting it to the time of evening when the sun is below the horizon. Alternatively, it could come from the word "twill", a type of textile weave that creates a sturdy fabric, or, it could be inspired by the French Étoile (said EH-TWAL), meaning "star".

      Associated with choreographer Twyla Tharp, a waitress in the television series Schitt's Creek, and a Monster High character Twyla Boogeyman, Twyla was also used by Toni Morrison in her short story, Recitatif, which was reissued in 2022.
