Master Word Decoding with Prefixes and Suffixes

You will learn how to decode words using affixes, which are word parts that change meanings. When you see a new word, you can break it into parts to figure out what it means. This skill helps you become a better reader and understand more words in your books.

Affixes include prefixes that come at the beginning of words and suffixes that come at the end. Learning about these word parts connects to Using Affixes To Find Word Meanings and helps you with Apply Phonics Reading And Spelling Skills.

Prefixes are word parts that come at the beginning of words. They change what the word means. When you see "un-" at the start of a word, it usually means "not" or the opposite.

For example, "unhappy" means "not happy." The word "unlock" means "not lock" or to open something. You can also find "re-" which means "again." The word "reread" means to read again, and "replant" means to plant again.

Other prefixes you might see include "pre-" which means "before," like in "premix" which means to mix before. Learning prefixes helps you with Decoding Prefix Suffix Words.

Suffixes are word parts that come at the end of words. They also change what words mean. The suffix "-er" often means "more" or "a person who does something."

When you add "-er" to "tall," you get "taller" which means "more tall." When you add "-er" to "teach," you get "teacher" which means "a person who teaches." The suffix "-ing" shows that something is happening right now, like "watering" means you are watering plants now.

You might also see "-able" which means "can be," like "bendable" means "can be bent." The suffix "-less" means "without," so "hopeless" means "without hope." These skills connect to Reading Words With Endings.

Affix: A word part that you add to the beginning or end of a word to change its meaning.

Prefix: A word part that comes at the beginning of a word, like "un-" or "re-."

Suffix: A word part that comes at the end of a word, like "-er" or "-ing."

Decode: To figure out what a word means by looking at its parts.

Root Word: The main part of a word without any prefixes or suffixes added.

Unhappy: Not happy; the opposite of happy using the prefix "un-."

Replant: To plant again using the prefix "re-."

Premix: To mix before doing something else using the prefix "pre-."

Teacher: A person who teaches using the suffix "-er."

Watering: The action of giving water to plants happening now using the suffix "-ing."

Bendable: Something that can be bent using the suffix "-able."

Hopeless: Without hope using the suffix "-less."

You can practice decoding words by looking for prefixes and suffixes in your reading books. When you find a word with "un-" at the beginning, think about what it means without that part.

Try making new words by adding "-er" to action words like "help" to make "helper." You can also practice with "-ing" by adding it to words like "play" to make "playing." This practice helps you with Decoding Single Syllable Words and Decoding Two Syllable Words.
