Prefixes and Suffixes
Introduction to Root words Word Parts Learning word parts will help you break down unknown words Why do we need to
learn word parts? Here's an example:

The prefix un added to the word happy makes a new word with a new meaning. The prefix un means not, so it changes the meaning of the word happy to not happy. A prefix is a word part placed in front of a base word.
A prefix usually changes the meaning of the base word. Un + Happy = UNHAPPY The most common prefixes are un- and re-. These two prefixes are the most useful for beginning spellers to learn because they appear frequently and their meanings are easy to understand.

Un means not (unhappy = not happy) or the reverse of or opposite of (as in untie).

Re means again (redo = do again) or back (as in repay). The Two Most Common Prefixes Words with Un-
Un + able = Unable
Un + believable = Unbelievable
Un + clean = Unclean Words with re-
Re + use = Reuse
Re + start = Restart
Re + send = Resend 1. The spelling of the base word never changes. Simply add the prefix to the beginning of the base word, as in the word unhappy.

2.The spelling of the prefix never changes. A prefix will be spelled the same no matter what base word it is attached to. For example, if you learn to spell the prefix poly, as in polygon, you can depend on poly to be spelled the same in the words polygraph, polyester, and polygram. Handy Tips for Adding Prefixes 3.Be aware that double letters can occur. If you add the prefix un to natural, both the prefix and the base word retain their original spelling. The result is unnatural. Take a look at these other words where double letters occur:
Il + Logical = Illogical
Im + mature = Immature
Il + Legal = Illegal Some words contain the same string of letters as a prefix, but upon closer examination you’ll find that they are not prefixes. The re- in real is not a prefix. Other examples include uncle, pretty, press, interest, reach, irony, dish, and antique. Watch Out!
Look out for prefix look-alikes. Suffixes are the endings of words. These are a letter or group of letters that end a word. For instance, the letter -s is commonly used to signal a plural word. Another example is -er which relates to a person or thing that does something.

Example 1: Folder + s = Folders (more than 1 folder)
Example 2: Fold + er = Folder (Something that folds)
Example 3: Fight + er = Fighter (Someone that fights) What are Suffixes? A root word is a linguistic unit. We use root words and add prefixes and/or suffixes to make new words.

Words with the same ROOT word belong to the same word family What are Root Words? Objective 1: Students demonstrate knowledge of root words, develop vocabulary skills, and
demonstrate creative-thinking skills.
Objective 2: Students will create real words by combining root words and/or short words. Here are some examples,
The root word is Acer, Acid, or Acri
The meaning of these root word is the same. It means Bitter, Sour, Sharp
Example of words are ACERBIC, ACIDITY, ACRID
The root word is Chrom
The meaning of this root word is color
Examples of words are Chrome, Polychrome, Chromatic In English, we have many Greek and Latin Root words. Any Questions????
