Lesson details

Key learning points

  1. The suffixes -ise and -ify often turn adjectives and nouns into verbs.
  2. When the root word ends in a consonant, we often just add the suffix.
  3. When the root word ends in a ‘y’, we remove the ‘y’ and add the suffix.
  4. When the root word ends in a vowel, we remove the final vowel and add the suffix.
  5. How to spell the curriculum words: exercise, criticise and consider.

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

  • Verb - a doing, being or having word

  • Adjective - describes a noun

  • Noun - a naming word for people, places or things

Common misconception

Pupils may spell words with -ize, how the suffix sounds and in the American spelling.

Discuss the difference between the American and British spelling of the suffix -ise.

As a class, you could build lists of words over time by brainstorming or collecting from shared texts, to show how nouns, adjectives and verbs can be formed from each other.
