      Creating adjectives using the suffixes -ful and -less

      Lesson details

      Learning outcome

      I can spell adjectives using the suffixes -ful and -less.

      Key learning points

      1. The suffixes -less and -ful create adjectives.
      2. The suffix -ful means ‘full of’ or ‘having qualities of’ and the suffix -less means ‘without’ or ‘lacking’.
      3. The suffixes start with a consonant. This means the root word usually doesn’t change when the suffix is added.
      4. If the root word ends in a consonant +y, then the ‘y’ is replaced by ‘i’ before the suffix.
      5. How to spell the curriculum words: awkward, bruise, regular and therefore.

      Keywords

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

      • Suffix - a letter or group of letters added to the end of a word to change its meaning

      • Adjective - describes a noun

      Common misconception

      Pupils may think the suffix is spelt with a double 'l' like the word 'full'.

      Explicitly point out the difference between the spelling of 'full' and the suffix 'ful'.

      Teacher tip

      Model applying unfamiliar words in simple sentences to expose pupils to the meaning. They may be unfamiliar with words such as 'merciless', 'penniless' and 'thankless'.
