Silent letters explained for parents (Australia)
Silent letters are letters that sit in the spelling but do not make a sound when you say the word. In knee, you hear /n/ … /ee/ — the k is quiet. In write, you hear /r/ … /igh/ … /t/ — the w is quiet. In lamb, you hear /l/ … /a/ … /m/ — the b is quiet. Australian Prep to Year 4 classrooms teach these as patterns (kn-, wr-, -mb, light -gn and silent h), not as one "weird English" pile.
That is a different job from magic e / CVCe. Magic e's silent final e is quiet on purpose so the vowel says its long name (cake). Silent-letter patterns like kn- and wr- are consonants that stay quiet while the rest still sounds out. Keep the tools separate: quiet letter that changes the vowel (magic e) vs quiet letter that is not sounded in a known pattern (this page).
Silent letters also differ from a consonant digraph (sh = one glued sound), a consonant blend (st = each sound heard), soft c and soft g, vowel teams, and r-controlled / bossy r.
This guide covers early silent-letter patterns, magic-e contrast, oral then print, short home games, light links to tricky / heart words and spelling morphology, and where they sit from phonics into decodables and the Year 1 Phonics Check.
Silent letters vs magic e vs digraph vs blend
Mixing these labels causes homework friction. Keep the tools clear:
| Pattern | What it is | Sounds | Example |
|---|---|---|---|
| Silent letter pattern | Letter present in print, not heard | Rest of word sounds out | k in knee; w in write; b in lamb |
| Magic e / CVCe | Silent final e | Long vowel; e quiet | cake → /k/ /ay/ /k/ |
| Consonant digraph | Two consonants | One glued sound | sh in ship |
| Consonant blend | Two/three consonants | Each sound heard | st in stop |
| Soft c / soft g | c or g before e/i/y | /s/ or /j/ | cent, gem |
| Vowel team | Two vowels | One vowel sound | ai in rain |
| R-controlled | Vowel + r | One r-coloured vowel | ar in car |
Kitchen examples: knee (silent k), write (silent w), lamb (silent b), cake (magic e), ship (digraph), stop (blend).
So knee has four letters and two heard sounds (/n/ /ee/). The k is in the spelling pattern; it is not a spoken phoneme. Sounding out every letter including the quiet one is the sticky habit this page helps unwind.
Early silent-letter patterns Australian parents will see
Programs vary. Start with the banks your school is teaching this fortnight. Common Prep–Year 4 sets:
kn- (silent k)
- knee, knife, know, knock, knit, knot
- Later: knew, known, knob
wr- (silent w)
- write, wrong, wrap, wrist, wreck
- Later: wrote, written, wriggle
-mb (silent b)
- lamb, thumb, climb, comb, crumb
- Later: bomb, numb, plumber (when ready)
-gn (silent g) — light touch
- sign, gnat (if taught). Later: sign ↔ signal is morphology — linked, not owned here.
Silent h — light touch
- hour, honest (often tricky / heart words first). Leave ghost / rhyme until knee and write feel steadier.
Honest note: some silent-letter words sit on heart-word lists early. Pattern teaching and heart practice can both be true — this page owns the patterns, not memorisation lists.
Why Australian schools teach silent letters after CVC and digraphs
Most Australian programs build CVC blending first (cat, sit), add digraphs and often blends, then introduce silent-letter patterns so know, write and lamb can be read without picture-guessing (why children guess words). The Australian Curriculum: English Foundation expects blending, segmenting and letter–sound knowledge — silent letters sit on that Prep–Year 4 path.
In parent language: hear sounds (phonemic awareness, rhyming, syllables) → phonics → CVC → digraphs → blends → often magic e, soft c/g, vowel teams and r-controlled vowels → silent-letter patterns (this page) → decodables, tricky / heart words, then fluency.
Exact order varies. Ask which silent pattern is on this fortnight's focus. Prep reading covers Foundation; kn-, wr- and -mb often deepen through Years 1–4. Where states use a Year 1 Phonics Check, taught silent-letter words may appear.
Oral stretch first, then print
Silent letters are easier when the ear leads the eye — same spirit as segmenting phonemes.
Oral first
- You say knee slowly: /n/ … /ee/. Child echoes, then squashes into knee. No /k/ in the spoken stretch.
- Contrast twins where you can: night vs knight (same sounds, different spellings when ready); rap vs wrap; no vs know.
- Finger stretch: one finger per heard sound. Knee gets two fingers. Lamb gets three. Write gets three (/r/ /igh/ /t/).
Then print
- Show k n e e. Point to the quiet letter: "The k is in the spelling; we do not say it. We start with /n/."
- Same for w r i t e: "Silent w — start with /r/." (If magic e is already taught, you can also note the long i — but do not turn this into a magic-e lesson.)
- Child says each heard sound, then blends through. Celebrate skipping the quiet letter correctly, not a letter-name chant of every printed letter.
- Practise one pattern bank at a time (kn- week before mixing wr- and -mb).
If print turns the game tense, drop the letters and go back to oral /n/ … /ee/ for knee. Oral first. Same spirit as homework without tears.
Home games (5 minutes, keep it friendly)
Stop while it is still playful. Prefer spoken games before print. Use the sound, not only the letter name ("/n/", not only "N").
- Quiet letter hunt — say a word; child holds up a quiet finger if they hear a silent-letter word from this week's bank: knee, write, lamb, cat (no), knock.
- Heard-sound fingers — stretch thumb: three fingers (/th/ /u/ /m/). Then show the print and find the quiet b.
- Robot talk — stretch "/n/ … /ee/"; child says knee. Then swap.
- Sort the cards — kn- / wr- / -mb piles: knee, write, lamb, knife, wrong, climb.
- Silent vs magic e — knee (quiet k, short/long as taught) vs cake (quiet final e that changes the vowel). Two different jobs.
- Pattern vs heart word — if know is also on the tricky list, say: "Pattern kn- helps; heart practice helps too." Light link only — see tricky / heart words.
- Book echo — on a familiar decodable, stretch one taught silent-letter word orally, then look at the letters if ready.
Prefer books that match taught patterns. Untaught silent-letter words invite guessing.
What "going fine" can look like (generous variation)
By late Prep through Year 4, many children can hear that knee starts with /n/ not /k/, read and spell a growing kn-, wr- and -mb set, stretch by heard sounds (not one finger per letter), notice silent letters in decodable text without freezing, and keep magic e's quiet e in a separate mental box from kn- / wr- / -mb.
Timelines vary — multilingual homes included. Soft sketch only. Watch CVC, digraphs, blends, magic e, soft c/g, vowel teams, r-controlled and fluency too (Prep reading; reading milestones Prep to Year 2; Year 2 reading).
When silent letters stay sticky (careful, non-medical)
If silent letters still feel random after teaching and light home play — knee read with /k/, write with /w/, lamb with /b/, or every printed letter forced into a sound — talk kindly with the teacher. Share concrete examples ("says /k/ at the start of knee"). That helps more than "phonics is weak".
Check foundations: phonemic awareness and segmenting, CVC, digraphs, blends. Silent letters sit on top of those (beside magic e, soft c/g, vowel teams and r-controlled on many sequences). Morphology (sign / signal) can wait — see spelling morphology.

FAQ
What are silent letters in phonics?
Letters in the spelling that are not heard when you say the word — k in knee, w in write, b in lamb. Taught as patterns, not as random exceptions only.
Are silent letters the same as magic e?
No. Magic e is a silent final e that makes the vowel long (cake). Silent-letter patterns like kn- and wr- are quiet consonants in known spellings. Different jobs.
Is a silent letter the same as a digraph?
No. A consonant digraph is two consonants → one sound (sh). A silent letter is present in print but not part of the spoken sound stretch.
Should we teach silent letters before or after CVC?
After secure CVC blending, and usually after digraphs (and often blends). Cat and ship before knee and write. See blending CVC.
How do silent letters link to tricky / heart words?
Some silent-letter words appear on heart-word lists early (know, hour). Pattern teaching still helps when the school introduces kn-, wr-, -mb. This page owns patterns; memorisation lists live on the tricky / heart words guide.
What about sign and morphology?
Light only here. Sign has a silent g; related words like signal can make the g heard again — that is morphology, not this page's deep dive.
Will flashcards alone fix sounding out quiet letters?
Rarely. Oral stretch of heard sounds, clear "this letter is quiet" talk, one pattern bank at a time, and matched decodable text beat endless cards.
