Boy Names That Can Start with a C or a K

Boy Names That Can Start with a C or a K
Many names for boys (and girls too) can start with either a C or a K. The C and K spellings have become basically interchangeable. Typically, the K spelling is the variation, although that is not always the case. Names such as Cai and Cale have spawned from Kai and Kale. In some cases, both spellings are equally legitimate, such as with Cillian and Killian, or Caspar and Kaspar.

Along with Kai and Killian, other boy names that can start with a C or a K in the US Top 1000 include Cairo and Kairo, Cash and Kash, Colton and Kolton, and Crew and Krew. Those in which both spellings are rare include Caius and Kaius, Cato and Kato.

The choice of C or K as an initial may reflect your feelings on name style, traditionality, and image. Here, a selection of boy names that work with either C or K as a first letter.

    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.

Having hot characters named Carter on both Gossip Girl and The OC probably didn't hurt, and for fifteen years on ER" Noah Wyle's Dr. John Carter was always called by his last name. Carter also, of course, has presidential cred.

    "helpful, pillow"

CianHeart

  • Origin:

    Irish
  • Meaning:

    "ancient"

    A handsome Irish name for boys, very popular in that country, but in the US this traditional spelling might cause pronunciation problems. Still, whether Cian or Kian, it's simple and straightforward enough for the initiated. Cian is rising in the British popularity charts. This was the name of several legendary figures, including Cian, son of the god of medicine. His own son was Lugh, the sun god and father of the Ulster warrior Cuchulain and Cian is also the name of the son-in-law of the high king Brian Boru. So very well connected.
