You met one silent letter already: the e on the end of cape. There are others, and they behave differently.
Step 1: Let's Learn
Read it, or press Listen and follow the words.
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.
You hear: /k/
A digraph — one new sound instead
| Letters | c and k — two letters |
|---|---|
| Sounds you hear | 1: /k/ |
| Can you hear c’s own sound? | Yes — /k/ is in there |
| What is missing | two letters but only one /k/ |
| So it is | A 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.
- Step 1
She tries /k/ /n/ /ee/ and gets "k-nee".
Recognizing the Pattern
Sam meets wrist, wrong and wrap in one page.
- Step 1
The first one puzzles him.
Where the k Went
Ana asks why knee has a k.
- Step 1
Hundreds of years ago people said "k-nee".
Step 4: Your Turn
Practice makes it stick.

What You Learned
- Some letters are written and never said.
- They come in patterns: kn, wr and mb.
