Silent letter words are words with one or more letters you write but do not say, like the k in knight, the b in debt and the p in psalm. This guide lists 150 common silent letter words sorted from A to Z, explains why English keeps letters nobody pronounces, and gives you a simple plan to practice them at home, in class or before a spelling bee.
Silent letters are one of the biggest reasons English spelling feels unfair. You can hear a word perfectly and still miss it, because the sound gives no clue that a g, h or w is hiding inside. The good news is that most silent letters follow a small number of patterns. Learn the pattern once and you can spell dozens of words with it. If sound-alike pairs are also giving you trouble, our homophones list covers 120 of them.
What are silent letter words?
A silent letter is a letter that appears in a word's spelling but is not pronounced. In island, the s is silent. In lamb, the b is silent. Some silent letters change the sound of a nearby vowel even though they make no sound themselves, like the final e in cake that makes the a say its name. In this guide we focus on the letters spellers actually forget: the ones that sit quietly in the middle or at the start of a word.
Here is a quick way to tell: say the word slowly and clap each sound. If the spelling has a letter that no clap matches, that letter is silent.
Why does English have silent letters?
There are three main reasons, and knowing them helps you guess spellings you have never seen.
- Pronunciation changed, spelling did not. The k in knight, knee and know was once pronounced. According to Etymonline, the kn- sound was fully voiced in Old and Middle English and had faded to a plain n sound by about 1750. The spelling had already been fixed, so the k stayed.
- Scholars added letters to match Latin. In Middle English, debt was spelled dette. Later writers added a b to make it look like the Latin word debitum. The b was never spoken in English. Doubt has the same story.
- Borrowed words kept their original spelling. Words that came from Greek, like psalm and psychology, keep a p that English speakers do not say. French loans like ballet and rendezvous keep silent final letters.
When you meet a new word in a spelling bee, asking for the language of origin can point you toward one of these patterns.
Silent letter words from A to Z
Below are the most useful silent letters, each with examples. The silent letter is the one in bold in the heading.
Silent B words
The silent b usually comes after m at the end of a word, or before t.
- climb, comb, crumb, dumb, lamb, limb, numb, plumb, thumb, tomb, womb, bomb
- debt, doubt, subtle
Silent C words
A silent c often follows s, as in sc before e or i.
- scene, scent, science, scissors, muscle, fascinate, descend, ascent, crescent, discipline
Silent D words
- Wednesday, handsome, handkerchief, sandwich (in many accents), grandson, hedge, ledge, bridge, badge, edge
In -dge words the d is not heard as a separate sound; it simply marks the short vowel before the j sound.
Silent G words
The silent g shows up in gn at the start or end of a word, and in gh.
- gnat, gnaw, gnome, gnarled, sign, design, foreign, reign, campaign, align
- high, sigh, night, light, though, daughter, neighbor, weigh
Silent H words
- hour, honest, honor, heir, ghost, rhyme, rhythm, rhino, what, when, where, why, while, school, chorus, chemistry, echo, exhaust
A silent h after r is a strong clue that the word came from Greek, as in rhyme and rhythm.
Silent K words
Silent k words almost always start with kn.
- knee, kneel, knife, knight, knit, knob, knock, knot, know, knowledge, knuckle, knack, knapsack
Silent L words
The silent l often sits before k, m, d or f.
- talk, walk, chalk, stalk, yolk, folk, calm, palm, salmon, almond (in many accents), half, calf, could, would, should
Silent N words
A silent n follows m at the end of a word.
- autumn, column, condemn, hymn, solemn, damn
Notice how the n comes back when you add a suffix: autumnal, columnist, hymnal, solemnity. Thinking of the longer word is a great way to remember the silent letter.
Silent P words
- psalm, psychology, pseudonym, pneumonia, pterodactyl, receipt, cupboard, raspberry, corps
Silent S words
- island, isle, aisle, debris, corps, viscount
Silent T words
The silent t is common in -sten and -stle endings.
- listen, fasten, glisten, moisten, often (in many accents), castle, whistle, thistle, wrestle, hustle, bustle, Christmas, mortgage, ballet, buffet, gourmet
Silent U words
A silent u often follows g to keep the g hard.
- guess, guest, guide, guilt, guitar, guard, biscuit, building, build, tongue, plague, league, colleague, vague, rogue
Silent W words
Silent w often comes before r at the start of a word, and in a few other spots.
- wrap, wreck, wren, wrench, wrestle, wrist, write, wrong, wrote, wrinkle, answer, sword, two, who, whole, whose
That is roughly 150 examples across the letters spellers most often miss.
Silent letter patterns at a glance
| Pattern | Silent letter | Examples | Memory hint |
|---|---|---|---|
| kn- at the start | k | knee, knife, know | If it starts with an n sound, try kn |
| wr- at the start | w | write, wrong, wrist | Many wr- words are about twisting |
| gn- at start or end | g | gnome, sign, reign | Think of the longer word: signal |
| -mb at the end | b | lamb, climb, thumb | m + b like "my bee" at the end |
| -mn at the end | n | autumn, column, hymn | The n returns in autumnal, columnist |
| ps-, pn- at the start | p | psalm, pneumonia | Greek origin |
| -stle, -sten | t | castle, listen | Common in older English words |
| gu- before e or i | u | guess, guide | The u keeps the g hard |
| rh- | h | rhyme, rhythm | Greek origin |
Silent letter words for kids: 25 starters
Younger spellers do best with short, concrete words they already say every day. Start with these:
- knee, knot, knock, know, knife
- lamb, thumb, comb, climb, crumb
- write, wrap, wrong, wrist, two
- hour, ghost, what, when, where
- half, talk, walk, island, listen
A good routine is three words a day. Say the word, write it, then circle the silent letter in a different color. Ask your child to say the word "the spelling way," pronouncing every letter out loud (k-nee, lam-b), then the normal way. This "spelling voice" trick is a favorite of teachers because it gives the silent letter a sound the brain can hold on to.
Tricky silent letter words for older students and adults
These trip up strong spellers because the silent letter is in the middle of the word or the word is less common:
- rhythm: silent h, and no vowel after the y sound until the end
- pneumonia: silent p at the start
- mortgage: silent t
- subtle: silent b
- indict: silent c (sounds like "in-dite")
- victuals: pronounced like "vittles"
- colonel: sounds like "kernel"
- Wednesday: silent d and, for many speakers, a silent first e
- handkerchief: silent d
- solemn: silent n
- heir: silent h
- plumber: silent b
If you are preparing for an adult or school bee, add these to your study cards and test them in both directions: hear the word and spell it, then read the spelling and say it. For more competition-level traps, see our list of difficult spelling bee words.
How to remember silent letters
Rote memorizing 150 words is slow. These methods work faster:
- Use the related word. Sign has a silent g, but signal and signature say it. Bomb hides a b that bombard pronounces. Muscle hides a c that muscular pronounces.
- Learn the pattern, not the word. Once you know kn- and wr-, every new word with those starts is easier.
- Say it the spelling way. Pronounce the silent letter on purpose while you study (Wed-nes-day), then switch back to normal speech.
- Group by family. Study all the -mb words in one session and all the -stle words in another.
- Ask for the origin. In a spelling bee, a Greek origin makes ps-, rh- and pn- more likely; a French origin makes a silent final t more likely.
Silent letters in a spelling bee
Silent letters are exactly the kind of trap that an oral bee rewards careful spellers for avoiding. Spellers can usually ask the pronouncer for the definition, the part of speech, a sentence and the language of origin. Our guide to the spelling bee pronouncer explains what you can ask and when. A few habits help:
- Ask for the origin when a word starts with an n, r or s sound that could hide a k, w or p.
- Picture the word written down before you say the first letter.
- Spell slowly. Saying "k" before "n" takes a moment of confidence, and rushing makes spellers drop it.

A two-week silent letter practice plan
Week 1: patterns
- Day 1: silent k (kn-) and silent w (wr-)
- Day 2: silent b (-mb, -bt) and silent n (-mn)
- Day 3: silent g (gn, gh) and silent h
- Day 4: silent l, silent t and silent u
- Day 5: mixed quiz of 20 words read aloud
Week 2: mixed and harder words
- Day 6: Greek-origin words (psalm, rhythm, pneumonia)
- Day 7: related-word pairs (sign/signal, autumn/autumnal)
- Day 8: tricky adult list above
- Day 9: write a short story that uses 10 silent letter words
- Day 10: final quiz of 30 words, then re-test only the misses two days later
Keep a "missed words" card and add a word every time it trips you up. That short personal list is often more useful than any printed one.

Silent letters are one trap; the doubling rule before -ing and -ed is another.
Frequently Asked Questions
What are silent letter words?
Silent letter words are words with a letter you write but do not pronounce, such as the k in knee, the b in lamb and the w in write. Most come from older pronunciations or borrowed spellings.
Which letters are most often silent in English?
The silent letters spellers meet most are b, c, g, h, k, l, n, p, t, u and w. Silent k in kn- words and silent w in wr- words are among the most common starter patterns.
Why does English have silent letters?
Mostly because pronunciation changed while spelling stayed fixed, as with the k in knight. Some letters, like the b in debt, were added to match Latin, and borrowed Greek or French words kept their original spelling.
What is a silent letter word for kids?
Good first examples are knee, lamb, write, hour and thumb. They are short, everyday words, so children can focus on spotting the silent letter.
How do you teach silent letters?
Teach one pattern at a time, like kn- or -mb, and have students circle the silent letter. Saying the word the spelling way, with every letter pronounced, helps the silent letter stick.
Does every English word with a silent letter follow a rule?
No. Many follow patterns such as kn-, wr- and -mb, but words like colonel and Wednesday have to be learned on their own. Adding them to a personal missed-words list is the quickest fix.
