Key learning points

  1. The suffix -cial is common after a vowel letter.
  2. The suffix -tial is common after a consonant letter.
  3. Words ending in the suffix -cial or -tial are generally adjectives.
  4. Exceptions include: financial, commercial, provincial.
  5. How to spell the curriculum words: occur, occupy and communicate.

Common misconception

Often the root of the word is hard to spell so this leads to incorrect spellings.

Discuss words that children find hard and look for root words that you recognise, or parts of the word that are difficult.
