ABSTRACT
Root Words – sometimes called base words – are the main part or stem of a word. They can be words in themselves. They can take a prefix or suffix, or both. The root word here is ‘sign’:
resign signal designer
Prefixes are (groups of) letters that go at the beginning of a word and change its meaning:
deform inform perform reform uniform
Suffixes are (groups of) letters that go at the end of a word and change its meaning and the way it is used:
loves loved loving lover loveable
Most topics have three sections, with different levels of activities to match the individual’s development and skills.
