English KS2: Prefixes

A fun, animated guide explaining how prefixes can usually be added to the beginning of words without any changes to the spelling of the root word.

Examples are given of the prefixes 'un-', 'dis-' and 'mis-' being added to the beginning of different root words to create a new word with a negative meaning.

The different spelling rules that need to be remembered for adding the prefix 'in-' are demonstrated; explaining that the 'n-' can change into 'l', 'r' or 'm', depending on the initial letter of the root word.

Rule 1 explains that for words beginning with 'l', the prefix 'in' changes to 'il-'.

Rule 2 explains that for words beginning with 'r', the prefix 'in-' changes to 'ir-'.

Rule 3 explains that for words beginning with 'm' or 'p', the prefix 'in-' changes to 'im-'.

The rules are visually demonstrated to help pupils remember them.

This short film is from the BBC series, Wonderful Words, a series of animated clips to support vocabulary knowledge.
