Affixes in Grammar-Definition, Types, Examples, and Usage

What are Affixes in English Grammar?

In English grammar, an affix is a bound morpheme, meaning it cannot stand alone as a word but attaches to a base word (root) to create a new word or change its grammatical function.

What are Types of Affixes?

Here are the different types of affixes with examples:

1. What are Prefixes?

Prefixes are affixes that are added to the beginning of a word to modify its meaning.

Examples of Prefixes in Grammar

Affixes and their meaning become easier to understand when you see how affixes in a sentence change the base word. Here are some common prefixes and examples of words that use them:

• Un – unhappy, undo, unfair
• Dis- disagree, disconnect, disapprove
• Re- redo, rebuild, reorganize
• Pre- prefix, preheat, preview
• Post- postdate, postgraduate, postmortem
• In-  inactive, incomplete, indirect
• Im- impossible, imperfect, impatient
• Il- illegal, illegible, illogical
• Mis- misunderstand, misinterpret, mislead
• Over-  overlook, overcook, overestimate

2. What are Suffixes?

Suffixes are affixes that are added to the end of a word to modify its meaning.

Examples of Suffixes in Grammar

Here are common suffixes and their usage in words:

• Ful- joyful, careful, colorful
• Able-comfortable, notable, lovable
• Less- hopeless, useless, endless
• Ment– excitement, development, requirement
• Ness– happiness, kindness, darkness
• Tion- adaptation, attention, explanation
• Er-teacher, runner, singer
• Est– biggest, tallest, happiest
• Ive- creative, effective, informative
• Ly- quickly, happily, slowly

3. What are Infixes?

These are affixes added within a word to modify its meaning. Infixes are inserted within the middle of the word stem.

English grammar does not use infixes in its standard form. Infixes are more common in other languages like Tagalog, Malay, and several Native American languages.

4. What are Circumfixes?

These are affixes that are added to both the beginning and end of a word to modify its meaning.

In English, circumfixes are a relatively rare type of affix.

Examples of Circumfixes in Grammar

Here are some examples of English words that use circumfixes:

• En-en – Enlighten (The circumfix is “en-…-en” which means “to put into a certain state”. The root word is “light”)
• Be-ed – Befriended (The circumfix is “be-…-ed” which means “to make or cause something”. The root word is “friend”)
• En-ed – Enriched (The circumfix is “en-…-ed” which means “to make or cause something”. The root word is “rich”)
• Em-en – Embolden (The circumfix is “em-…-en” which means “to put into a certain state”. The root word is “bold”)
• En-d – Enraged (The circumfix is “en-…-ed” which means “to cause someone to be in a certain state”. The root word is “rage”)
• Be-ed – Bejeweled  (The circumfix is “be-…-ed” which means “to adorn or cover with something”. The root word is “jewel”)
