1. Root, Prefix, Suffix
RPS System

2. The root is the main part of the word to which other parts can be attached.
Example: biology
Root = bio = life
Biology = the study of life.
Example #2: Biography
Biography = a book about someone’s life
Roots

3. More Examples:
Geo = earth
Micro = small
Opt = eye
Phobia = fear
Phon = hear
Try to think of some words with these root words. What are their meanings? Note: Not all roots will be at the beginning of the word. For example: “telephone” includes the root “phon.”

6. Affixes Affix = letters added to a word root.
There are two types of affixes:
A) Prefix: Letters added before the root.
B) Suffix: Letters added after the root.
Affixes

7. Prefix Prefix examples: Un = not Unlucky = not lucky
Uncooked = not cooked

8. Prefix More examples: Anti = against Dis = not Mis = incorrect
Re = again
Sub = under
Trans = across
For the prefixes given, try to brainstorm words that include them and their possible meanings.

1) The teacher predicted that the student would make an A.
A) guessed the result before it happened.

11. Suffix Suffix examples: Suffix = -or, -er, -ar = a person who

16. This is what we will aim for
This is what we will aim for. Holidays, other assignments, or testing could disrupt it, but we are going to strive to stay relatively consistent to do the following:
1) Receive a worksheet on Monday for the week. Worksheet will include 6 words that have roots, prefixes, and affixes, and you will focus primarily on analyzing the word for roots and prefixes.
2) Practice using the words on Wednesday. Work in pairs to analyze a text and determine word meanings based on roots and prefixes.
3) Take a quiz on Fridays to assess the roots and prefixes analyzed.
