What does affix mean in a word?

An affix is a word element that is added to the beginning (prefix) or end (suffix) of a word to change its meaning or grammatical function.

Here's a breakdown:

* Prefix: Added to the beginning of a word.

* Example: "un-" in "unhappy" changes the meaning from "happy" to "not happy."

* Suffix: Added to the end of a word.

* Example: "-ing" in "walking" turns the verb "walk" into a present participle.

Affixes can be used to:

* Change the meaning of a word:

* Example: "pre-" in "pre-game" means "before"

* Change the grammatical function of a word:

* Example: "-er" in "teacher" changes the verb "teach" into a noun

* Create new words:

* Example: Combining the prefix "un-" with the word "happy" creates the new word "unhappy."

Here are some common affixes:

Prefixes:

* un- (not)

* re- (again)

* pre- (before)

* in- (not)

* dis- (not)

Suffixes:

* -ing (present participle)

* -ed (past tense)

* -er (one who does something)

* -ly (in a certain way)

* -ness (state of being)

Understanding affixes can help you decipher the meaning of unfamiliar words, break down complex words into simpler parts, and expand your vocabulary.
