What Are Adjectives that Start with K?

The letter K can be traced back to the Greek letter Kappa, which came from the Semitic Kaph. Prior to that, a form of K appeared in Egyptian hieroglyphs where it represented the word “hand.” When Greek words were absorbed into Latin, the letter C replaced the K. As a result, the Romance Languages (such as Italian, French, and Spanish) infrequently use the letter K. In the 12th Century, however, K was reintroduced and replaced the letter C at the start of words that had a palatal velar. This is the hard “kuh” sound at the start of words such as kid, king, kitchen, and kitten.

In English, the letter K is often silent (especially at the end of words). It is silent at the start of words when it is followed by the letter N. Some examples are:

  • Known
  • Kneed
  • Knightly

At the beginning of words, K is usually pronounced “Kuh” or “Kay.”
