Dyslexia and spelling: why it stays hard and what helps
In short
Spelling is often the hardest skill for people with dyslexia, and it can stay hard even after reading improves. Spelling needs every sound and letter in order, from memory. Explicit teaching of sounds, patterns and word parts helps, along with spell-check and fair grading.
Why is spelling so hard with dyslexia?
To read a word, you only have to recognize it. To spell it, you have to recall every letter in the right order. That takes a strong link between the sounds in a word and the letters that spell them, which is exactly where dyslexia causes trouble.
English spelling makes it harder. Many sounds have more than one spelling, like the long a in rain, play, cake and eight. A child with dyslexia needs to learn these patterns directly and practice them many times.
What do common spelling errors mean?
| Error | Example | What it can show |
|---|---|---|
| Missing sounds | "sop" for stop | Trouble hearing every sound in a word |
| Letters out of order | "form" for from | Trouble holding the sound order in memory |
| Sound-alike swaps | "bes" for pets (b for p) | Mixing up sounds that are made alike in the mouth |
| Spelled by sound | "rane" for rain | Sounds are there; the spelling pattern isn't yet |
| Same word, many ways | "becuz", "becos", "because" | The word isn't stored in memory yet |
Errors that show all the sounds, even if the spelling is wrong, are a good sign. They mean your child can hear the sounds. The next step is learning the right patterns.
Does spelling get better as reading improves?
It does get better, but more slowly. Many people with dyslexia become good readers and stay weak spellers for life, and that's normal. Spelling needs more exact memory for words than reading does.
Don't judge your child's reading by their spelling. A child can read a word correctly and still spell it wrong in their writing.
How should spelling be taught?
The same way reading should be taught for dyslexia: clearly, step by step, and with lots of practice. Children learn the sounds, then the letters that spell them, then patterns and rules, then word parts like prefixes and suffixes.
- Spell only patterns that have been taught.
- Say the word, tap or count the sounds, then write a letter for each sound.
- Practice a few words at a time, then use them in a sentence.
- Review old patterns every day so they stay strong.
- Teach common word parts, like -ed, -ing and un-, as units.
How can you help with spelling at home?
Keep practice short and kind. Use the words or patterns from school. Say a word, have your child repeat it and tap the sounds on their fingers, then write it. Check it together, letter by letter.
- Parent
- Spell "trip". Say it and tap the sounds.
- Child
- /t/ /r/ /i/ /p/. Four sounds.
- Parent
- Great. Write a letter for each sound.
- Child
- T, r, i, p.
- Parent
- Check it. Touch each letter and say the sound. Did you get all four?
A personal spelling list can help too. Keep a short list of words your child often uses and often misspells, like friend or because. Practice a few at a time and cross them off when they stick.
What supports help in school?
- Grading written work for ideas, not spelling, except on spelling tasks.
- Spell-check and word prediction on a computer or tablet.
- A personal word wall or spelling card for common tricky words.
- Speech-to-text tools for longer writing.
- Shorter spelling lists based on taught patterns.
These supports let your child show what they know, but they don't replace spelling teaching. Both should happen in the same school year.
Should my child use spell-check?
Yes, for everyday writing. Spell-check lets children with dyslexia write more and worry less. It has limits, though. It may miss words that are spelled wrong but form another real word, and it may not guess the right word if the spelling is far off. Better spelling skills make spell-check work better too.
Which spelling patterns cause the most trouble?
Vowels cause the most trouble, because English has many ways to spell each vowel sound. Long vowel spellings like ai, ay, a-e and eigh are hard to keep straight, and so is the quiet vowel sound in the middle of longer words, as in the second syllable of pencil. Endings like -tion, -le and -ed are tricky until they are taught as units.
Small, common words can be surprisingly hard too. Words like said, was and because don't follow the usual patterns, so they need extra practice. A good teacher will point out which part of the word is tricky and which parts follow the rules, so your child only has to memorize the odd part.
