5 letter first names

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.

Caius is classical and serious but also has a simple, joyful quality. There was a third century pope named Caius, as well as an early Christian writer, several Shakespearean characters, and a Twilight vampire. We would pronounce the name to rhyme with eye-us though at Cambridge University in England, where it's the name of a college, it's pronounced keys.

Dulcy is a charming feminine name with English origins, typically considered a diminutive form of Dulcie or Dulcibella. These names derive from the Latin 'dulcis,' meaning 'sweet' or 'gentle.' The name evokes qualities of sweetness, kindness, and warmth through both its meaning and its soft sound. Dulcy has never been widely popular but maintains a quaint, vintage appeal that occasionally resurfaces in naming trends. Its relatively uncommon usage makes it distinctive without being difficult to pronounce or spell. Dulcy's old-fashioned charm gives it a nostalgic quality reminiscent of earlier eras, particularly the early 20th century. The name carries pleasant associations with sweetness while remaining unpretentious and approachable.

Estée is a feminine name with French origins, most famously associated with cosmetics entrepreneur Estée Lauder, whose birth name was actually Josephine Esther Mentzer. The name is believed to be a stylized form of Esther, a biblical name meaning 'star' in Persian. Estée has an elegant, sophisticated quality with its French accent mark and simple, melodic sound. Though relatively uncommon as a given name, it carries associations of beauty, entrepreneurship, and luxury due to the Lauder connection. The name's brevity makes it distinctive yet accessible, combining classical roots with a modern, cosmopolitan feel. Estée provides a graceful alternative to more common names like Esther or Estelle.

Two drawbacks: some unpleasant World War II associations, and the Santa clause.

This nickname-name is very popular in Germany, though Lottie is still the preferred version in the US. The problem, of course, is that you'll have to put up with a lotta jokes. See?

Oscar is one of the most stylish Old Man Names of our era. While it's softened slightly in popularity over the past 20 years, that may be considered a very good thing.

Reign is one of a new, ahem, kingdom of word names that suggest a high-born child, joining Royal, Lorde, Titan, Saint, King, Princess, and Noble. We predicted this kind of defining name to be the Number 1 baby name trend of 2015...two weeks before Kourtney Kardashian and Scott Disick named their third child, a boy, Reign. Reign is as appropriate for girls as for boys. The female version is often spelled Rain -- or Raine or Rayne -- though that makes is more nature and less royal word name. Reign entered the US Top 1000 for the first time in 2016.
