Suffixes

Suffixes are groups of letters added to the end of a word to change its meaning or how it's used. They're like little word Lego pieces that can completely transform a word!

Here's the breakdown:

 * They change a word's meaning: Adding "-er" to "teach" gives you "teacher" (someone who teaches).

 * They change a word's part of speech: Adding "-ly" to "quick" turns the adjective "quick" into the adverb "quickly".

 * They can even show if a word is plural: Adding "-s" to "cat" makes it "cats".

Types of Suffixes

 * Derivational: These suffixes create entirely new words, often changing the part of speech.

   * Examples: "-ness" (sad -> sadness), "-ment" (agree -> agreement), "-able" (read -> readable)

 * Inflectional: These suffixes don't create new words, but they do change how a word is used grammatically.

   * Examples: "-s" (cat -> cats), "-ed" (walk -> walked), "-ing" (run -> running)

Common Suffixes and What They Do

 * -er / -or:  Often indicates a person who does something (teacher, actor)

 * -ly: Often turns adjectives into adverbs (quickly, sadly)

 * -ness: Often turns adjectives into nouns (happiness, kindness)

 * -tion / -sion: Often used to form nouns (information, discussion)

 * -ing: Can make verbs into adjectives (running shoes) or nouns (the act of running)
