Silent K Words

There are many letters that we see and write but do not pronounce. These silent letters are a challenge. But there are many patterns we can learn to make reading and pronunciation easier. Silent K is a common pattern. 

If you see a word that starts with KN-, you only pronounce the N. So knight sounds exactly the same as night and knot is pronounced exactly the same as not. Notice that this is very similar to the pattern for silent G words.

Like many silent letters, the K was not always silent. In Old English, the word knight was once cniht and knot was once cnotta, and the K sound at the beginning used to be pronounced, up until about the 17th century. But because the K-N combination is difficult to pronounce, over hundreds of years we elided it until it disappeared completely. In many other Germanic languages, the K is still pronounced in related words.


Here's a word list with 15 examples of silent K words.
