Silent Letters and the ie / ei Choice

B2.1About 40 minutes
Learning goals
  • I can spell words with silent letters, like kn, wr, mb and gn, and I know where they usually appear.
  • I can use a related word to remember a silent letter, like sign and signal.
  • I can choose ie or ei using the long e and long a clues, and I know the common exceptions.

Words to know

silent letter
A letter you write but don't say, like the k in knee.
related word
A word from the same word family, like sign and signature.
exception
A word that doesn't follow the usual pattern.

Letters that keep quiet

Say knee, write and lamb. You hear /n/, /r/ and /m/, but you write kn, wr and mb. These words have silent letters.

Long ago, people said these letters. The k in knee was spoken hundreds of years ago in English! The way people talk changed, but the spelling stayed the same. That's why we still write them.

Where silent letters live

Silent letters follow position patterns, just like the spellings you already know. Some like the beginning of a word. Others like the end.

PatternWhereSaysExamples
knBeginning/n/knee, knife, knock, know, knot, knit
wrBeginning/r/write, wrong, wrist, wrap, wreck
gnBeginning or end/n/gnaw, gnome; sign, design
mbEnd/m/lamb, climb, thumb, comb, crumb
mnEnd/m/autumn, column
stle, stenEnd/sul/, /sun/castle, whistle; listen, fasten
hBeginning or after g, r(silent)hour, honest; ghost, rhyme
Common silent letter patterns
kneeshh!silent k at the beginningsays /nee/writeshh!silent w at the beginningsays /rite/lambshh!silent b at the endsays /lam/autumnshh!silent n at the endsays /AW-tum/
The dashed boxes are silent letters. kn and wr live at the beginning of a word; mb and mn live at the end.

Remember igh

The gh in night, light and high is silent too. You learned it as part of the igh pattern for long i.

A related word can reveal the silent letter

Sometimes a silent letter speaks up in another word from the same family. If you know the related word, you know why the letter is there!

Worked example

Let's spell "design"

Spell /dih-ZINE/, as in I will design a poster for the winter carnival.

  1. Split it: de · sign.
  2. The second part sounds like sine, but think of the word family: sign, signal, signature. They share the base sign.
  3. In signal you can hear the g. So sign keeps its g, even when it's silent.
  4. de + sign = design.

design. The silent g comes from the base sign.

ie or ei?

Many writers get stuck on words like field and receive. You may have heard this rhyme:

**i before e, except after c, or when it says /ay/, as in neighbour and weigh.**

The rhyme works best when the letters say long e (/ee/) or long a (/ay/). Here's how to use it:

When the sound is...UseExamples
/ee/ (long e)iebelieve, field, piece, chief, niece, shield, brief
/ee/ right after ceireceive, ceiling, receipt
/ay/ (long a)eieight, weigh, neighbour, sleigh, vein, reindeer
The ie / ei clues
What sound do ie / ei say?/ee/ (long e)/ay/ (long a)Right after c?noyesiefield, pieceeireceive, ceilingeieight, weigh
The ie / ei clues as a tree. Start at the top: first listen for the sound, then check whether it comes right after c.

Rule breakers

A few common words break the rule. Learn them by heart: weird, seize, protein, either, neither. A silly sentence helps: Neither weird scientist could seize the protein!

Worked example

Let's spell "receive"

Spell /rih-SEEV/, as in Did you receive my letter?

  1. Split it: re · ceive. The second part says /seev/ with a long e.
  2. The /s/ sound here is spelled with c, like ceiling.
  3. Long e right after c: use ei, not ie.
  4. Add ve at the end (English words don't end in v).

receive (r-e-c-e-i-v-e).

Worked example

Let's spell "piece"

Spell /peess/, as in May I have a piece of bannock?

  1. The vowel says long e.
  2. It doesn't come after c, so use ie: pie...
  3. The /s/ at the end is spelled ce. (Memory trick: a piece of pie!)

piece

Just for fun

Knock, knock.

Who's there?

K.

K who?

Exactly! The k in knock never says anything either.

Hands-on activity

Silent letter detectives

You need: paper, a pencil, a highlighter or crayon, and a book or newspaper.

  1. Make a chart with three columns: Beginning, Middle, End.
  2. Search your book for words with silent letters. Write each word in the column that shows where its silent letter is. Highlight the silent letter.
  3. Look for patterns. Which column has words with kn and wr? Which has mb?
  4. Pick two words from your list. Can you find a related word where the silent letter is heard? (Try sign/signal, soft/soften.)
  5. Write five ie/ei words on small slips of paper with the vowels left blank, like f _ _ ld and rec _ _ ve. Swap with a family member and fill them in.

For parents and teachers

Big idea: This lesson supports B2.1 (using related words and morphemes to spell) and builds on the position-based spelling tendencies children practised in Grade 3. Silent letters often follow position patterns (kn, wr at the start; mb at the end), and many are explained by a related word (sign/signal, muscle/muscular).

How to help at home:

  • When your child misspells a silent-letter word, ask: "Is there a related word where we can hear that letter?"
  • Teach the ie/ei rhyme with its limits: it's about the long e and long a sounds, and a handful of words break it.
  • Spot silent letters on signs and packages: Knock, Wrap, Comb.

Common difficulties:

  • Leaving out silent letters (nee, rite, lam). Practise the patterns by position.
  • Applying ie/ei to every ie or ei word, including words where the letters don't say long e or long a (science, their, friend). The rule is a clue, not a law.
  • Note on bannock in the example: it is a bread made in many First Nations and Métis communities, and enjoyed across Canada.
