Prefix, Base Word, Suffix Quiz

Understanding Word Parts

• A base word is a standalone word with meaning, such as "help".
• A suffix is a word part added to the end of a word, such as "-ful" in "helpful".
• A prefix is a word part added to the beginning of a word, such as "un-" in "unhelpful".

Breaking Down Words

• To break down a word, identify its prefix, base word, and suffix.
• For example, "unhelpful" can be broken down into "un-" (prefix), "help" (base word), and "-ful" (suffix).

Creating New Words

• New words can be created by adding prefixes and suffixes to base words.
• For example, adding the prefix "un-" to the base word "do" creates the word "undo".
• Adding the suffix "-ful" to the base word "help" creates the word "helpful".
