On the first page of this worksheet you’ll find twenty root words. They all make sense on their own, but they could all have either a prefix (a letter string that goes at the beginning of a word) or a suffix (a letter string that goes at the end of a word) added to them. On the second page you’ll find twenty prefixes and suffixes. You need to cut out all these cards and then work out which prefix or suffix goes with each root word. To make things harder, we are not telling you which are suffixes and which are prefixes!
