Prefixes & Suffixes (Intro) — Answer Key
Part A: Sort the Words
Sort each word or number into the correct category box.
1. Sort each word by its affix. Place mis- words (prefix meaning 'wrong') in A, and -ly words (suffix meaning 'in a way') in B.

Part B: Fill in the Blank
Write the missing word or number on each line.
1. Please walk slowly so you do not slip on the wet floor.
The suffix -ly turns slow into an adverb that tells how you walk.
2. My sister ran quickly to catch the school bus.
Quick + ly = quickly, meaning 'in a quick way'.
3. I did not mean to misplace my library book on the bus.
The prefix mis- means 'wrong', so misplace means to put something in the wrong place.
4. Be careful not to misread the instructions on the test.
Mis- plus read creates misread, meaning to read something incorrectly.
5. The puppy wagged its tail happily when we came home.
Happy + ly becomes happily, an adverb meaning 'in a happy way'.
Part C: True or False?
Read each statement. Circle True or False.
1. The prefix mis- means 'wrong' or 'badly'.
True False
Mis- adds the idea of doing something wrong, as in misspell or mistake.
2. The suffix -ly usually makes a word an adverb.
True False
Adding -ly to an adjective usually turns it into an adverb that tells how.
3. The word misplace has a suffix, not a prefix.
True False
Mis- appears at the beginning of misplace, which makes it a prefix.
4. Loudly means 'in a loud way'.
True False
The suffix -ly turns loud into loudly, an adverb meaning 'in a loud manner'.
