Verb, adjective and noun suffixes

Unit Summary

In this unit, pupils learn spelling and grammar conventions associated with certain verb, adjective and noun suffixes like -ing, -ed, -s, -ies, -es, -ves, -ate, -en, -ify and -less. Pupils review and learn more examples of how the addition of a suffix can affect the grammar of a word.

Lesson Summary

You will learn to spell words using the suffixes -ify and -ise.

Key Notes

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