Why Can My Child Spell a Word One Day and Forget It the Next?

If your child remembers a spelling for the test but forgets it later, they might be relying purely on visual memory. Discover how to build durable spelling skills.

Quick Answer: A child may remember a spelling temporarily for a test without having fully learned the sound-letter relationships or spelling patterns within the word. Helping them notice sounds, letter patterns, and meaningful word parts—and retrieving the word again over time—can support more durable spelling learning.

It is a common frustration for parents: your child practises a list of words all week, spells them perfectly on Friday, but misspells them in a sentence the following Tuesday.

This often happens because spelling is widely misunderstood as a purely visual memory task. While practice is absolutely useful, simply staring at a word and copying it repeatedly does not guarantee that the word will stick in a child's long-term memory.

Beyond Visual Memory: How Spelling Works

According to foundational literacy research, such as the work on orthographic mapping by Ehri (2014), learning to spell involves much more than memorising shapes. Children need to connect the sounds they hear in a word (phonemes) to the letters that represent those sounds (graphemes).

When a child understands these phoneme-grapheme relationships—alongside common spelling patterns and word structures—they build a much stronger orthographic representation of the word. As Treiman (2017) notes, spelling is a linguistic task, not just a visual one. Memorising weekly word lists can be a helpful part of practice, provided children are also learning why words are spelled the way they are.

5 Practical Ways to Support Spelling at Home

You can help your child move beyond rote memorisation by encouraging them to analyse words:

• Say It Slowly: Before writing, ask: "What sounds can you hear?" Encourage them to stretch the word out aloud.
• Break It Into Sounds: Help them identify the individual sounds (phonemes) in the word, matching each sound to a letter or group of letters.
• Look for the Pattern: If they are learning a specific rule, compare related spellings to reinforce the pattern (e.g., light / night / right).
• Build Word Families: Explore words that share useful spelling patterns or meaningful word parts (morphology) to show how words are connected.
• Retrieve It Later: Instead of having them copy a word five times in a row, test their retrieval over time. Ask: "Can you spell that word again without looking?" If they struggle, respond to the mistake constructively by looking at the sounds together again.

"Spelling Bee": Practising Letter Patterns

At BornFab, our primary mission is to provide an educational learning platform for children aged 6–11. We believe that consistent, interactive practice helps reinforce what children are learning in school.

Spelling Bee is an entertaining educational game providing spelling practice within BornFab's English learning experience. By giving children opportunities to hear words and engage with their spellings in a focused, gamified environment, the game supports the ongoing retrieval and practice necessary for durable learning.

Frequently Asked Questions

Why does my child forget spellings they knew yesterday?

Often, children memorise the visual shape of a word just long enough to pass a test. If they haven't connected the sounds in the word to the specific letters (orthographic mapping), the spelling is easily forgotten.

Is memorising spelling lists enough?

Practice is important, but rote memorisation on its own is usually inefficient. Children learn best when they understand the sound-letter relationships and spelling patterns that make up the words on their list.

Should children sound out words when spelling?

Yes. Identifying the individual sounds (phonemes) in a spoken word is a critical first step. Once they can isolate the sounds, they can work out which letters represent those sounds.

How can I help my child practise spelling without simply copying words?

Instead of passive copying, encourage active retrieval. Ask them to write the word from memory, break words into sounds, and group words that share similar spelling patterns (like 'train', 'rain', and 'brain').
