Prefix worksheets A prefix is placed at the beginning of a word to modify or change the word's meaning. For example the prefix over can be put in front of confident to make a new word, overconfident. Prefixes are one of those subjects that many children find fascinating as it gives them an insight into the roots of words they use on a daily basis, as well as helping in guessing the meaning of new words they come across. In the new English Programme of Study for 2014 prefixes are introduced as early as Year 1, (‘un’ is introduced in Year 1 where there is no change in the root word e.g. do and undo.) A great deal more work is done on prefixes in Years 3 and 4 using ‘re’, meaning again or do again as in resubscribe,  ‘sub’, meaning below or underneath as in submarine,  ‘inter’, meaning between as in international,  ‘tele' meaning distance as in telephone as well as many others. We are delighted to announce that we have just published a series of worksheets on prefixes, which explain their meanings and provide plenty of practise with their usage. Some of these are suitable for younger children but many of these words with prefixes are quite hard, such as autobiography and telepathy. I really like these pages as they really do help with building a larger vocabulary as well as being fun to work with. Other prefixes include 'dis', 'mis', 'pre', 're', 'ir', 'il', 'sub' and 'inter'.
