      Spelling words with the superlative suffix -est

      Lesson details

      Learning outcome

      I can apply spelling rules to spell words with the superlative suffix -est.

      Key learning points

      1. If the root word ends in 'y', remove the 'y' and add -iest.
      2. If the root word ends in 'e', remove the 'e' and add -est.
      3. If the root word contains a short vowel sound, double the consonant and add -est.
      4. 'Most' is irregular because it does not follow the same pattern. The comparative 'more' becomes 'most'.
      5. How to spell the curriculum words: secretary and controversy.

      Keywords

      • Suffix - a letter or group of letters added to the end of a root word

      • Root word - the base word from which other words are formed often by adding prefixes or suffixes

      • Superlative - the form of an adjective or adverb that indicates the highest degree of a quality when comparing three or more things

      Common misconception

      Pupils can think the -est suffix is spelt 'ist' or 'st' because that is what you can hear.

      Review pupils' misconceptions after practice tasks. Even though the word can sound different, -est is always spelt in the same way.

      Teacher tip

      Contextualise spellings by using superlative adjectives in sentences. Look at comparative adjectives alongside superlative adjectives and talk about irregularities such as 'good', 'better', 'best' and 'bad', 'worse', 'worst'.
