Definition of Prefix

A prefix is defined as a letter/letters added at the beginning of the word to make a new word. It is also defined as an affix that is placed in front of the word to form a new word. Adding the affix changes the word into another word. The new form of the word sometimes gives the same meaning and sometimes gives a new meaning.

Examples of Prefixes Words  

Prefix: The word ‘prefix’ by itself is an example of a prefix. It is made up of two words "pre and fix". Pre means before and fix means attach. They both form a new word ‘prefix’ which means to attach an affix in front of the word.

Oversight: The word oversight is formed by adding the prefix ‘over’ to the word sight. Sight means the act of looking or observing. The meaning of the ‘over’ is a high place. When the prefix ‘over’ is added in front of ‘sight’ that forms a new word oversight. Oversight means watching or observing someone.

Insight: The word sight means an act of looking or observing. When ‘in’ is added as a prefix, it becomes insight. Insight means looking deeper into the center or feeling of understanding.

Hyphen with Prefixes Words

Do we use a punctuation mark (hyphen) between affix and prefix? Rules are different about using a hyphen. It is better to consult a dictionary if you are not sure.

When a prefix is added to a proper noun, we hyphenate the prefix.

• Anti-American
• Pro-Pakistan
• Pre-World War

When the last letter of a prefix and the first letter of an affix are the same, you need to hyphenate. You may not use a hyphen when it is ‘o’.

• Re-entry
• Re-enter

You need to use a hyphen with special prefixes such as ex, and self.

• Self-conscious
• Self-respect
• Ex-president

Sometimes you need to hyphenate the prefix in order to clarify the reader. Sometimes a word creates confusion or gives a different meaning in one case.

• Re-cover
• Re-press

You can use some prefixes in both forms. It depends upon the writer whether to use a hyphen or not.

• Antigovernment
• Anti-government
