Topic: Root words and affixes (Prefixes and Suffixes) What are root words? A root word is a basic word with no prefix or suffix added to it (a prefix is a string of letters that go at the start of a word; a suffix is a string of letters that go at the end of a word). By adding prefixes and suffixes to a root word we can change its meaning.
What are prefixes? A prefix is a part of a word or a word, within a word. It is put at the start of another word to make a different meaning. It can also mean a number that is put in at the start to show which number something is in a group. It is a type of affix(an addition to the base form or stem of a word in order to modify its meaning or create a new word.).
