      Adding the suffix -ate to words

      Lesson details

      Learning outcome

      I can turn adjectives and nouns into verbs using the suffix -ate.

      Key learning points

      1. A suffix is a letter or group of letters at the end of a word which creates another word and can change the word class.
      2. The suffix -ate often turns adjectives and nouns into verbs.
      3. When the root word ends in a consonant, we often just 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: business, possession and answer.

      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

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

      • Verb - a doing, being or having word

      Common misconception

      Pupils may not know the meaning of words encountered in the lesson.

      Ensure to gloss the meaning of all vocabulary used in the lesson and say in full sentences to help embed the meaning.

      Teacher tip

      When identifying word class, always put the word in the context of a sentence. A helpful strategy is to subsitute the word for a synonym within the sentence to identify the word class. We need to **formulate** a plan. We need to **make** a plan.
