The document explains the concepts of prefixes and suffixes in language, detailing how they can be added to base words to create new meanings. It provides examples of various prefixes and suffixes, including their meanings and how they modify root words. Additionally, the document includes exercises for practice in identifying and using prefixes and suffixes.

1. Prefix and suffix
• A base word can stand alone and has meaning (for example,
help).
• A suffix is a word part added to the end of a word (for
example, -ful).
• If you add the suffix -ful to the base word, help,
the word is helpful.
• A prefix is a word part added to the beginning of a word or
base word (for example, un-).
• If the prefix un- is added to helpful, the word is unhelpful.
