Decoding unfamiliar words
Read Y3-4 exception words with unusual spelling-sound correspondences, applying growing knowledge of morphology and etymology to decode unfamiliar exception words
What a learner can do afterwards
- Read exception words from the Y3-4 statutory word list accurately (e.g. 'business', 'caught', 'knowledge', 'different')
- Identify unusual letter-sound correspondences in exception words and explain why the word does not follow common GPC rules
- Use growing knowledge of morphology and etymology to attempt unfamiliar exception words (e.g. recognise the root 'know' in 'knowledge')
The lesson
Some words break the usual reading rules. You cannot always sound out every letter and get the right word. These are called exception words. The best way to read them is to spot the tricky part, and remember it, or work out why it is spelled that way.
Look at 'knowledge'. It has a silent k at the start, because it comes from the old word 'know'. If you know that 'know' has a silent k, you can guess 'knowledge' does too. 'Business' hides the word 'busy' inside it: busi-ness. That is why business has an i where you might expect a y.
The word 'caught' uses the letters 'augh' to make an 'or' sound, an old spelling pattern you also see in 'daughter' and 'taught'. You cannot sound out each letter here. You just have to remember that 'augh' says 'or'.
When a word looks strange, try this: look for a smaller word hiding inside it, remember any similar-looking words you already know, and if that fails, just learn the tricky part by heart.
Exception words break the rules, so look for a hidden root word, spot spelling patterns you have seen before, and remember the odd bits.
