Doubling the consonant with suffixes: -ing, -ed, -er, -est and -y

Lesson details

Learning outcome

I can spell words by doubling the consonant with suffixes: -ing, -ed, -er, -est and -y.

Key learning points

  1. A suffix is a letter or group of letters at the end of a word which creates another word.
  2. If the root word has a short vowel and a single consonant, the consonant letter is doubled when the suffix is added.
  3. The letter 'x' is never doubled, such as words like mixing, mixed or boxer.

Keywords

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

  • Short vowel - a vowel sound that sounds short when spoken like "a" in "cat" or the "o" sound in "hot"

  • Consonant - a sound that is made by blocking air in the mouth with the teeth, tongue, lips or palate

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

Common misconception

Pupils often miss the double letters in the middle of words that have a suffix.

Drawing attention to the patterns of how words are spelt when suffixes are added will help them to remember the double letter.

Teacher tip

Practise the phonic techniques of stretching words to separate the phonemes in order to help identify if a word has a short vowel in it.
