Silent Letters: gn, mb and bt
Fifteen words with silent letters: gn (gnome, gnat), mb (lamb, climb, thumb) and bt (doubt, debt). Answer key included.
Download PDFA LAMB has a silent letter at the end. A GNOME has one at the start. And DOUBT carries a ghost in the middle that nobody hears at all. After kn and wr, this puzzle gathers the next three silent-letter patterns — and shows children that English ghosts come in every position.
This word search contains fifteen words across three silent-letter families: gn (GNOME, GNAT, GNAW, SIGN), mb (LAMB, COMB, CLIMB, THUMB and six more) and bt (DOUBT, DEBT). It is designed for Year 3 and Year 4 pupils continuing their KS2 silent-letter work, and for third and fourth grade readers in the US. Compact grid since most words are short, words left-to-right and top-to-bottom only.

Three silent letter patterns in one puzzle
The mb family is the largest and the most rewarding to teach. Every word ends in mb — LAMB, COMB, THUMB — and the B is always silent. Better still, the family makes its own little rhyming set: NUMB, DUMB, CRUMB, THUMB all rhyme, all share the silent B, and the rhyme itself is the memory hook. After kn from S44 and wr from S45, children meet a third ghost letter without having to learn three rules — just three positions.
The gn family is smaller. The G is silent at the start (GNOME, GNAT, GNAW) and once in the middle (SIGN). And the bt family is tiny on purpose: DOUBT and DEBT are the only two common cases, both inherited from French via medieval scribes who added the B to show off the words’ Latin roots. Children love hearing this — the B was put in deliberately by someone who never expected anyone to read it aloud. Spelling’s strangeness has reasons; the reasons are often a thousand years old.
Five words to remember
- THUMB belongs to the hand they are searching with. Have your child hold up theirs while spelling the word. The silent B sits where the thumb sits — a final flourish that does nothing audible.
- CLIMB the rhyming family. Ask your child to find the four mb words that rhyme with NUMB. (DUMB, CRUMB, THUMB.) Then ask which mb word doesn’t fit — CLIMB rhymes with TIME, not NUMB. A family with one outsider is more memorable than a tidy one.
- SIGN has a relative without a ghost. Write SIGN and SIGNAL on a line. The G stays silent in SIGN but speaks again in SIGNAL — the suffix wakes it up. Silent letters are silent by position, not by personality.
- DOUBT was a fashion statement. Tell your child the B was added on purpose, by scribes who wanted to flaunt the word’s Latin grandparent. Spelling is sometimes showing off in slow motion — and DOUBT has held the pose for six hundred years.
- GNAW is what a beaver does. Or a mouse, or a dog with a bone. Ask your child to mime gnawing while spelling the word. The G stays silent; the teeth do the work.
Three ways to spot the ghosts
As a three-column sort. Three columns on the board — silent at the start, silent at the end, silent in the middle. Pairs sort the fifteen grid words. Most land at the end (mb words dominate), gn words split between start and middle (SIGN is the wanderer), and DOUBT and DEBT keep each other company in the middle. The visual layout makes the structure of the lesson visible.
As a wake-the-letter pairs game. Pairs hunt for words where the silent letter reappears in a longer relative — SIGN/SIGNAL, BOMB/BOMBARD, CRUMB/CRUMBLE. (Most children will need help with the second list; that’s the value.) When the suffix arrives, the ghost wakes up. A profound little fact about English, delivered through detective work.
One-to-one at home. For home educators: make a haunted-house word collection on a piece of A4. Three doors drawn on a house — one for start-ghosts, one for end-ghosts, one for middle-ghosts. Every time your child meets a new silent-letter word in reading this week, they add it through the right door. The page grows over a fortnight, and your child realises spelling is full of words they have been mispronouncing in their head all along.
