Affixes (Roots, Prefixes, and Suffixes) Webquest


We have been studying how roots can change the meaning of a word.  That is how we can know that the root 'cogn' means to know.  It's how we can tell if we know a person or not based on the words used to describe them.  For example, somebody may be incognito (in disguise, unknown) or if we recognize a person (we know them).  The prefixes and suffixes added into the words help us determine the meaning of each word.

Check out this video for more information and more examples!



We are tracking down the meaning of roots and other affixes today! 

1) Before you start, grab your notebook and divide the page into 3 columns.  In the first column, you will label it 'Affix (Root, Prefix, Suffix)', in the second you will label it with 'Meaning', and in the third column you will label it with 'Example'. 

2) You will find links and words associated with those links.  In each link, you should be finding either a certain amount of words or particular words.  Each link will come with specific directions to help guide you through it.

3) When you find the words, you will copy those words down on a lined sheet of paper in the appropriate column.  This paper will be turned in for a grade at the end of the day.

4) Rewatch the original video (or click below) and copy down 5 examples of a root word, prefix, or suffix.  Fill in all of the categories.

5) At the end of your webquest, answer one of these questions fully and  in complete sentences.  You may answer an extra one for 5 points worth of extra credit

  • Choose a new word (or several new words) that has been added to the dictionary recently, and research the new word. How did this word get “invented”? What does it mean? Why was it added to the dictionary?
  • Merriam Webster (a dictionary publisher) posts words on their website that people submit to be included in the dictionary. These are words that are not yet included in the dictionary. You can see the list at Choose some of these new words and write about why you think that these words should or shouldn’t be added to the dictionary.
  • Why is the letter “W” called “double-u” and not “double-v”?
  • "-ology" means "the study of".  Explore various -ologies at and meet over 100 different Ologists from Arachnology to Ornithology.  Write about the different -ologies you explore (at least 2 minimum).
  • How did shapes get their names?



This is worth 35 points in total.  The breakdown is as follows:

1) There are 20 rows to fill in (1 point each).

2) There are 5 more rows which are up to the students to fill completely with affixes from the last video (10 points).

3)  The question at the end is answered fully and in complete sentences (5 Points).

Extra credit is available for 5 points if two of the ending questions are answered instead of 1.
