How to spell KNOW
K-N-O-W
KNOW has 4 letters. The fastest way to make it stick is a picture: a Kettle, then a Nut, then an Otter, and so on through the word.
Your child can say know perfectly and still spell it wrong, and that is not carelessness — it is the word's fault. KNOW hides a letter that never makes a sound, so "sound it out", the advice every parent reaches for first, is the one strategy guaranteed to fail here. What works instead is a picture that puts the missing letter somewhere your child can see it.
Say it, break it, build it
Before the story, give the word a shape. KNOW is short enough to say in one piece, so the work is in the letters rather than the chunks:
KNOW
- Say it. Read KNOW out loud together, slowly, stretching the sounds. Let your child hear where the word bends.
- Break it. Have them tap the sounds out on their fingers. Tapping turns a spelling into a physical thing, which is a second memory route alongside seeing and hearing it.
- Build it. Now bring in the story below. Each letter gets a character, and your child rebuilds KNOW by retelling the story rather than by trying to picture the word.
The KNOW story
K Kettle 🫖 — A bouncy Kettle is ready to help you remember KNOW!
Ask your child: What is ready to help you remember KNOW?
N Nut 🥜 — Kettle opens a box and out pops Nut!
Ask your child: What pops out of the box?
O Otter 🦦 — Nut turns into Otter!
Ask your child: What does Nut turn into?
W Worm 🪱 — Everyone celebrates with Worm!
Ask your child: What do they celebrate with?

Why this works: A silent letter has no sound to hang on to, so it needs a hook of a different kind. Giving it a character means the letter now exists as a thing in a story rather than as an absence in a sound, which is the only reliable way to remember something you cannot hear.
Why KNOW is harder than it looks
A letter you cannot hear
In KNOW, the K at the front is silent. Children spell what they hear, so the letter they cannot hear is the letter they leave out. That is why the story matters more than sounding it out for this word: the story puts the silent letter back.
It has a twin
KNOW sounds exactly like NO. Spelling it right is not about sound at all, it is about meaning, so the only thing that helps is a picture tied to what this particular version means.
A 5-minute routine for KNOW tonight
You do not need a worksheet or a full study session. This is the whole thing:
- Minute 1 — find the ghost. Before any story, say KNOW out loud together and ask your child which letter they cannot hear. Let them hunt for it. Finding the silent letter themselves is worth more than being told where it is ten times.
- Minute 2 — ask it back. Go through the prompts: "What is ready to help you remember KNOW?" Let your child answer from memory. If they stall, give the picture, not the letter.
- Minute 3 — write it. Have them write KNOW once, saying each character as they go. Once, not five times. Writing it repeatedly stops being retrieval after the first go and becomes copying.
- Minute 4 — break it on purpose. Write it wrong yourself and ask them to catch you. Spotting the error is harder than producing it, and children love being the one who is right.
- Minute 5 — leave it. Stop while it is still fun. Come back tomorrow for 60 seconds and again in three days. Spacing is what moves it into long-term memory; more minutes tonight will not.
If it goes wrong: when your child gets KNOW wrong on the third or fourth go, the answer is almost never more repetitions. Change the character instead. If Kettle is not landing, let them pick their own thing beginning with K — their own choice always sticks better than ours, and it hands them control of a task that usually happens to them.
The -ow family
Once KNOW is solid, it stops being one word and becomes a key. Every word below ends in the same -ow chunk, so your child already knows how to finish all of them — only the first sound changes:
blow · grow · show · slow · throw · flow
This is how spelling starts compounding. Say KNOW, then change only the first sound and ask what the new word is. Children find this genuinely fun, because they can hear themselves getting them all right, which is a rarer feeling in spelling practice than it should be.
Other words with silent letters
KNOW is not a one-off. These words fail in exactly the same way, so a child who cracks the pattern here gets the rest cheaper:
Questions parents ask about KNOW
How do you spell know?
KNOW is spelled K-N-O-W. The fastest way to make it stick is a picture: a Kettle, then a Nut, then an Otter, and so on through the word.
Why does my child keep getting know wrong?
In KNOW, the K at the front is silent. Children spell what they hear, so the letter they cannot hear is the letter they leave out. That is why the story matters more than sounding it out for this word: the story puts the silent letter back.
How long should we practise know?
Five minutes, then stop. Silent-letter words usually need one more review than average, because there is nothing in the sound to reinforce them between sessions. Two 60-second reviews later in the week will do more for KNOW than a longer session tonight.
Is this suitable for a Primary 1 or Primary 2 child in Singapore?
Yes. KNOW works with the weekly list your child brings home from school, and the method suits ages 5 to 8. Nothing here depends on a particular syllabus: type whatever word is on this week's list and the story is built for it.
My child made up their own story. Should I let them?
Let them, every time. A story your child invents is remembered better than one handed to them, because inventing it is itself an act of retrieval. Our version is a starting point, not the correct answer — if they replace every character with dinosaurs, the spelling still comes out right.
Any word. One story. Free.
