List of Words with Silent Letters
Sometimes I think the English language is just trying to mess with us. Honestly, teaching phonics is going smoothly. The kids are sounding out c-a-t (cat) and d-o-g (dog). They feel confident. They feel like readers.
And then, they open a book and see a picture of a man in shining armor on a horse. They look at the word under it, and they sound out: “Kuh-nnn-i-guh-huh-tuh.”
Knight.
Why is there a K? Why is there a G and an H? Why do we do this to children?
As a teacher, silent letters are one of the hardest hurdles. They defy the basic “sound it out” logic we teach in EYFS/Kindergarten. For my special needs students, these silent letters can feel like insurmountable brick walls in their reading journey. But here is the secret: they aren’t random. There are patterns.
Most silent letters are leftovers from history. Hundreds of years ago, we actually pronounced the K in “knee.” We pronounced the G in “gnat.” Over time, we got lazy and stopped saying them, but we kept the spelling. Other silent letters come from words we borrowed from French or Latin.
To help our kids master these, we need to stop treating them as random exceptions and start teaching them as groups. Here is a breakdown of the most common silent letter patterns to help you navigate homework time without pulling your hair out.
Words with Silent K (The “Kn” Pattern)
This is usually the first silent consonant pattern kids encounter.
The Rule: When a K comes before an N at the beginning of a word, the K is almost always silent.
I tell my students the K is “shy.” It stands in front of the noisy N, but it is too scared to make a sound.
- Knee: Part of your leg.
- Kneel: To go down on your knee.
- Knife: A tool for cutting.
- Knight: A soldier in armor.
- Knit: To make clothes with yarn.
- Knob: A handle on a door.
- Knock: To tap on a door.
- Knot: A tying of rope.
- Know: To have knowledge.
- Knowledge: Information you know.
Teaching Tip:
Have your child put their hand on their throat and say “Nnnn.” They will feel a vibration. Now have them whisper “Kkkk.” No vibration. It is hard to switch quickly from a quiet sound to a vibrating sound, so over time, we just stopped saying the K.

Words with Silent W (The “Wr” Pattern)
This pattern almost always happens at the beginning of action words (verbs).
The Rule: When a W comes before an R at the beginning of a word, the W is silent.
- Wrap: To cover something (like a gift).
- Wreck: To destroy something.
- Wren: A small brown bird.
- Wrench: A tool.
- Wrestle: A sport.
- Wrinkle: A line on skin or cloth.
- Wrist: The joint connecting hand and arm.
- Write: To put words on paper.
- Wrong: Incorrect.
Teaching Tip:
Focus on the action. “Use your wrist to write the wrong word.” Making silly sentences helps the pattern stick.
Words with The Silent B (The “Mb” Pattern)
This is a tricky one because it comes at the end of words. Kids will naturally try to explode that “buh” sound at the end.
The Rule: When a B comes after an M at the end of a root word, the B is silent.
- Bomb: An explosive weapon.
- Climb: To go up something.
- Comb: A tool for hair.
- Crumb: A small piece of food.
- Dumb: (Be careful with this one in school, it used to mean unable to speak, now means stupid).
- Lamb: A baby sheep.
- Limb: An arm or leg.
- Numb: Having no feeling.
- Thumb: The short, thick finger.
- Tomb: A grave.
The “Bt” Exception:
Sometimes B is silent before T, usually in older, more academic words.
- Debt: Money you owe.
- Doubt: Uncertainty.
- Subtle: Not obvious.
Words with The Silent G (The “Gn” Pattern)
This is less common in early reading books but shows up frequently by 3rd and 4th grade.
The Rule: When G and N are together, the G often stays quiet. This can happen at the start or end of a word.
- Align: To line up.
- Assign: To give a task.
- Design: A plan or drawing.
- Foreign: From another country.
- Gnat: A tiny flying insect.
- Gnaw: To chew on something hard.
- Gnome: A garden statue.
- Sign: A mark or notice.
Teaching Tip:
Teach related words. The G is silent in Sign, but it wakes up and makes a sound in Signature.
Words with The Silent H (Ghost Letters)
The letter H is very quiet. Sometimes it disappears entirely, especially at the start of words borrowed from French.
- Heir: A person who inherits something (sounds like “air”).
- Honest: Truthful.
- Honor: Respect.
- Hour: Sixty minutes.
Sometimes H is silent when it follows a G (the “Gh” pattern).
- Ghost: A spirit.
- Ghastly: Terrible.
The Most Important One: “Magic E”
I cannot write a post about silent letters without mentioning the most important one in elementary school: The Silent Final E.
Teachers often call this “Magic E” or “Bossy E.”
The Rule: The E at the end of a short word sits there silently, but it reaches over the consonant and makes the vowel say its own name (the long sound).
This is the bridge between reading simple words and complex words.
- Cap becomes Cape.
- Kit becomes Kite.
- Hop becomes Hope.
- Tub becomes Tube.
- Hug becomes Huge (It also makes the G soft!).
Practical Activities for Home or School
Don’t just give kids a list to memorize. Make them interact with the letters.
- Silent Letter Detectives: Give your child a highlighter and a page from an old magazine. Tell them they are hunting for “ghost letters.” Have them highlight every K that is next to an N, or every W next to an R.
- Word Surgery: Write words like “KNIFE” and “LAMB” on index cards. Have the child use child-safe scissors to cut off the letters they don’t hear. (This is great for kinesthetic learners).
- The “Magic E” Wand: Make a little wand out of a craft stick with an ‘e’ written on the end. Write CVC words (like ‘tap’ or ‘fin’) on a whiteboard. Have the child use the wand to add the E to the end and read the new word (‘tape’, ‘fine’).
Final Thoughts
If your child is frustrated by silent letters, validate that feeling. Tell them, “You are right. It makes no sense that ‘knife’ has a K. English is a weird language.”
Sometimes just knowing that it is weird, and that they aren’t crazy for being confused, gives them the confidence to keep trying.
Stick with it. Once they unlock these patterns, a whole new world of reading opens up to them.
