Silent K words
In English, there are many words in which the letter K is silent and not pronounced at all. These instances mostly occur when a word starts with the letter K and is followed by the letter N. They can also be found in compound nouns that use these words.
It is fascinating to note that in previous centuries the K in many of these words was not silent at all. For one reason or another this has evolved into the modern English language.
The non-pronunciation of silent letters is not naturally intuitive for children and ESL learners, it needs to be taught. On this page, there are words, flashcards, meanings of uncommon words, and practice sentences in which K is not pronounced to help you do this!
