Keywords

  • Prefix - a letter or group of letters added to the start of a root word to change its meaning

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

Common misconception

Pupils may think every word with a prefix will have a recognisable root word.

Show that some roots we don't recognise may have Latin roots that we don't know. We can call this a 'stem' or a 'root'. Recognising the prefix can still help with spelling and understanding.

You could play a definitions game as a whole class, where children provide a definition and challenge the class to find the right word.
