Prefixes are word parts added to the beginning of a base word. Suffixes are word parts added to the end of a base word. They change the meaning or form of the word.
Remember: prefixes and suffixes cannot stand alone. They must be attached to a base word to form a complete word.
A prefix changes the meaning of the base word by adding a new idea. For example, the prefix pre- means “before,” and the prefix re- means “again.”
When reading, look for a prefix at the beginning of a word. It often gives you a clue about the meaning.
A suffix changes the role or form of a base word. It can turn a noun into an adjective, an adjective into an adverb, or change tense in verbs.
Suffixes often change the part of speech. For example, “happy” (adjective) becomes “happiness” (noun).
These prefixes and suffixes appear often in fifth grade texts. Recognizing them will strengthen your vocabulary.
Some words may use the same prefix or suffix but carry slightly different meanings. Always read the whole sentence for context.
Applying prefixes and suffixes to base words can help you form and understand more advanced vocabulary.
If you can identify the prefix or suffix and connect it with the base word, you will better understand the meaning of unfamiliar vocabulary.
