Part 1 of 6Let's Learn

Step 1: Let's Learn

Read it, or press Listen and follow the words.

You met one silent letter already: the e on the end of cape. There are others, and they behave differently.

These ones do nothing at all

The silent e changed the vowel. The k in knee does not change anything. It is simply not said.

They come in patterns

kn at the start: knee, knife, know. wr at the start: write, wrong, wrap. mb at the end: lamb, thumb, climb.

Treat the pair as a unit

kn says /n/. wr says /r/. mb says /m/. Two letters, one sound — a digraph again.

So you can spot them

If a word starts kn or wr, you already know the first letter is silent. It is a pattern, not a surprise per word.

Why they exist

People used to say them. Knee really was said "k-nee" hundreds of years ago. The saying changed and the spelling stayed.

So they are leftovers, not decoration

You met this with the w in two. English spelling is often a record of how words used to sound.

Spelling them means knowing the pattern

If you hear /n/ at the start of a word and it is not spelled n, kn is the likely candidate. Patterns narrow the guess.

Step 2: Try It Yourself

Two letters, one sound — the same structure.

Look at ck: two letters and one sound. Silent-letter pairs work the same way.
ck

You hear: /k/

A digraph — one new sound instead

the soundduck
ck — as in duck
Lettersc and k — two letters
Sounds you hear1: /k/
Can you hear c’s own sound?Yes — /k/ is in there
What is missingtwo letters but only one /k/
So it isA digraph — two letters, one sound

ck is an odd one. It is a digraph, because two letters make one sound — but that sound is /k/, which is exactly what c says on its own. So you can hear c in there; what you cannot hear is a second sound for the k. Two letters, two letters but only one /k/.

Step 3: Watch an Example

One step at a time.

Reading knee

Ana meets the word knee.

  1. Step 1

    She tries /k/ /n/ /ee/ and gets "k-nee".

Recognizing the Pattern

Sam meets wrist, wrong and wrap in one page.

  1. Step 1

    The first one puzzles him.

Where the k Went

Ana asks why knee has a k.

  1. Step 1

    Hundreds of years ago people said "k-nee".

Step 4: Your Turn

Practice makes it stick.

A Word Starting kn

Problem 1 of 2

A word starts with kn. What do you know straight away?

Why the Letter Is There

Problem 2 of 2

Why does knee have a k nobody says?

Letters That Say Nothing

1 of 5

How is the k in knee different from the e in cape?

2 of 5

What sound does wr make?

3 of 5

What sound does mb at the end of a word make?

4 of 5

Why is knowing the pattern better than learning each word?

5 of 5

Why do silent letters exist?

Step 5: Quick Check

Show what you know.

  • Some letters are written and never said.
  • They come in patterns: kn, wr and mb.
  • Each pair is one unit making one sound.
