Silent Letters

Spell words with letters you write but do not say.

Some English words have silent letters. You write them, but you do not say them. Long ago, many of these letters were spoken.

Common silent letters include k before n (knee, knock, know), w before r (write, wrist, wrong), b after m (lamb, thumb, climb), and t in words like castle, listen and whistle.

To learn them, say the word in a funny way that sounds the silent letter (k-nock), then say it normally.
