How to Teach Irregular Words Without Rote Memorisation

If you’ve ever watched a child stare blankly at the word “said”after seeing it a hundred times on a flashcard, you know the frustration. Traditional rote memorisation — drilling whole words until they stick — is slow, boring, and often doesn’t work. The good news is there’s a better way, rooted in how reading actually develops in the brain.

Why Irregular Words Aren’t Really That Irregular

Here’s a fact that changes everything: most so-called “irregular” or tricky words are only partially irregular. Research into English orthography consistently shows that around 80% of the letters in common sight words follow normal phonics rules. Only one or two sounds in the whole word are genuinely unusual.

Take “said”: the s and d are completely regular — only the vowel ai saying the short-e sound is the tricky part. Or “come”: c and m are regular, and the ojust doesn’t respond to the magic-e patternthe way we’d expect. Once children see that most of the word is decodable, they only have one small piece to memorise.

The Partial-Alphabetic Strategy Explained

The partial-alphabetic strategy — sometimes called “phonics with exception flagging” — walks children through a word sound by sound, confirms what IS regular, then spotlights only the tricky part. It takes advantage of what children already know instead of asking them to start from scratch with every new word.

1. Decode what you can. Sound out every letter that follows the rules your child already knows from earlier phonics work.
2. Identify the exception.Name the one or two letters that don’t behave as expected.
3. Flag it visually. Underline, circle, or colour the tricky part so it stands out in memory.
4. Say the word. Put it all together and say the real pronunciation out loud, clearly and slowly.
5. Read it in context. Use the word in a sentence immediately so meaning reinforces the memory.

Studies comparing this approach to whole-word flashcard drills consistently find that children learn irregular words three to four times faster and retain them far longer. The reason is simple: they are using existing phonics knowledge as scaffolding rather than treating every word as a brand-new memorisation task.

A Word-by-Word Walkthrough

Here is the strategy applied to five of the most common tricky words. Read these aloud with your child if you can — the spoken walkthrough is just as important as the visual one.

• said— “S says /s/, d says /d/ — normal. The ai usually says /ay/ but here it says /e/. So we say said.”
• was — “W says /w/ — normal. The a says /u/ here, and the s at the end says /z/. So we say wuz.”
• the — “Th makes /th/ — a digraph we know. The e says /uh/ here. So we say thuh.”
• come— “C says /k/, m says /m/ — all regular. The o says /u/ instead of /oh/. So we say cum.”
• friend — “Fr is a blend we know, nd at the end is regular. The ie says /e/ here, not /ee/. So we say frend.”

In every case, the child feels competent for most of the word. That sense of “I know this bit” is crucial — it builds genuine confidence rather than the brittle performance that comes from pure memorisation.

Build the Right Foundation First

This strategy only works when children have phonics knowledge to draw on. Before tackling irregular words at scale, make sure your child is confident with single-letter sounds, basic CVC words, common word families, and at least some consonant blends. Without that scaffolding, tricky words feel overwhelming because there’s nothing to anchor the exception to.

The phonics stages by age guide is a good place to check where your child stands, and the reading readiness checklist can help you spot any gaps. Closing those gaps first means tricky words become much less tricky.

Multisensory Activities That Reinforce Tricky Words

Once you’ve introduced a word using the walkthrough, multisensory practice cements it. The more pathways the brain forms, the more durable and retrievable the memory becomes during real reading.

• Highlight and write. Write the word large, circle the tricky part in red, then copy it three times saying each sound aloud as you go.
• Magnetic letters. Build the word, then swap the tricky letters to compare. Build said then rearrange to sail to hear the vowel difference clearly.
• Sand or playdough. Tracing letters in sensory materials adds a tactile channel many children respond to strongly. See multisensory phonics activities for a full set of ideas.
• Digital practice. The flashcard gamelets children hear a word, see it, and respond — reinforcing the sound-to-print connection.
• Sound matching. The sound match gameis great for reinforcing which letters behave and which don’t, in a low-pressure game format.
• Memory match. The memory match gamepairs words with pictures, helping anchor meaning alongside form — especially useful for abstract sight words.

How Many Tricky Words to Teach at Once

Less is more. Research into working memory shows that introducing more than three to five new items in a single session causes interference — words blur together and none consolidates properly. A sustainable cadence looks like this:

1. Introduce one to three new words per session using the partial-alphabetic walkthrough.
2. Briefly review the previous session’s words first — retrieval practice beats re-exposure every time.
3. Only add new words once the child reads the previous batch fluently and without hesitation.
4. Revisit “mastered” words monthly — irregular words can fade without regular exposure in real reading.

This spaced approach means slower week-by-week progress but dramatically better retention over a term. It’s also far less demoralising for children who feel like flashcards are an endless treadmill with no finish line.

Sight Words vs Phonics: Clearing Up the Confusion

Many parents feel caught between two camps: the “just memorise sight words” approach and the “decode everything” phonics approach. As the sight words vs phonics explainer covers, they’re not opposites. Phonics gives children the tools to decode; irregular words are the small set of exceptions where decoding gets you 80% of the way and targeted memory covers the last 20%. Children taught this way don’t develop anxiety around “hard words” — because they always have a strategy to fall back on.

Your First Activity: The Tricky Spot Hunt

Try this today with any irregular word your child is struggling with. Write the word on paper in large letters. Ask your child to go through it sound by sound and circle every part that “makes sense” based on the phonological awareness and phonics they already have. Then ask: “Which part is the sneaky bit?” Let them colour it a different colour.

Children find this genuinely engaging because it turns a passive memorisation task into an active detective game. Once they’ve found the tricky spot, write the word correctly three times together, say each part aloud, then ask them to use it in a sentence. One word, five minutes — far more effective than twenty flashcard repetitions.

For a ready-made list to work through, the tricky words list organises common irregular words by phonics stage so you always know which ones match where your child is right now. And to assess overall progress, the phonics assessment at home guide walks you through a simple, no-stress check-in you can do at the kitchen table in under fifteen minutes.
