Rose is derived from the Latin rosa, which referred to the flower. There is also evidence to suggest it was a Norman variation of the Germanic name Hrodohaidis, meaning "famous type," and also Hros, "horse". In Old English it was translated as Roese and Rohese.

Sophia, which was the Number 1 girls' name in the US from 2011 to 2013, is among the top girl names in the Western World, with a sensuous sound and high-minded meaning. A real winner, Sophia reached the top of the charts without losing any—okay, much—of its sophisticated beauty.

Sophie is the French form of the Greek Sophia, for which it is also commonly used as a nickname. Given Sophia's long standing among the Top 10 girl names in the US, Sophie may feel more popular than it actually is.

Taylor was much more popular throughout the 1990s for both genders than it is today. Close to the Top 50 boys' names in the mid-1990s, Taylor recently fell out of the Top 500 for boys and out of the Top 100 for girls, and is predicted to continue on a downward trajectory for both genders. Similar but more stylish baby names today include Sawyer, Sayer and Thayer.

Fresher, brisker and, yes, cooler than Summer or Autumn or Spring, Winter is now a full-fledged female choice, especially since Nicole Richie and Joel Madden used it for daughter Harlow's middle name, and Gretchen Mol picked it as her daughter's first, as did media mogul Sean Parker. Winter continues to be the preferred spelling and has risen in popularity significantly over the past few years.
