What Are Prefixes and Suffixes?

• Prefixes and suffixes are groups of letters added to words.
• These letters are added to a main word, called a root word.
• A prefix is a word part attached to a word's beginning.
• A suffix is a word part attached to a word's end.
• Adding them creates a new word with a different meaning.

Learning Objectives

• Identify prefixes and suffixes and how they change a word's meaning.
• Break down new words into smaller parts to figure out their meaning.
• Use prefixes and suffixes to build new words and improve your vocabulary.

Introduction to Prefixes and Suffixes

• Prefixes and suffixes are like a secret code to unlock a word's meaning.
• A prefix is a word part that is added to the beginning of a word.
• A suffix is a word part that is added to the end of a word.
• The main part of the word is called the root word, like 'help' in unhelpful.
• In 'unhelpful,' the prefix 'un-' means 'not,' and the suffix '-ful' means 'full of.'
• This skill helps you understand new words and become a better writer.

Let's Learn with an Example

• Let's decode the word 'disagreement' by breaking it down into smaller parts.
• The root word is 'agree,' which means to share the same opinion as someone.
• The prefix 'dis-' at the beginning of the word means 'not' or 'the opposite of.'
• The suffix '-ment' at the end turns the action word into a noun.
• When we put all the parts together, we can understand the full meaning.
• A 'disagreement' is the state or result of not having the same opinion.
