[A familiarity with affixes and combining forms is important in attacking the pronunciation of a word and also in attacking the meaning of a word.

Most of the affixes are one syllable that can be attacked like any other syllable.]

You have seen how we can add endings to base words. The word "like" is a base word. If we add ed to "like," it becomes "liked." These endings don't change the basic meaning of the base word.

When we add a word part called an affix to a base word, the meaning is changed. An affix added on the front end of a base word is called a prefix. When we add the prefix dis to the front end of "like," what do we get? We get "dislike" which means the opposite of "like." Do you like ice cream or do you dislike it? Can you think of another word that starts with dis?

Script for Next Challenges We will read the sentence aloud together. I will point to the prefix at the left, say it, and say its meaning. You find the keyword in the sentence containing the prefix, say the word, and say the word without the prefix. Say and write the keyword in your Word Part Catalog and underline and say the prefix. Let's see how the prefix changes the meaning of the base word in the keyword.

CHALLENGE 1: The "not" prefixes.

dis-: I dislike the medicine. + distrust, dissatisfied

il-: It is illegal to jaywalk. + ill-mannered, illiterate

im-: His actions were improper. + imperfect, impractical

in-: His answer was incorrect. + inactive, insecure

ir-/ear/: He is an irresponsible ski bum. + irregular, irreplaceable

CHALLENGE 2: More "not" prefixes.

mal-: What caused the alarm to malfunction? + malformed, malpractice

mis-: I mistrust some politicians. + misguided, mismatch

counter-: Water will counteract the burning. + counterculture, countermove

anti-: He put antifreeze in the car. + antibiotic, antismoking

CHALLENGE 3: Seven prefixes. The general meaning of the prefixes below is enclosed in parentheses. The first five prefixes are open syllables ending with a long vowel sound. The last two have a weak vowel.

re-: (again): Frank will rewrite his letter. + redo, retell

pre- (before): The pizza is precut. + presold, pregame

co- (together): Fred's coworker is ill. + copilot, coanchor

be- (by): Will you stand beside me? + behead, becalm

a- (on): The empty boat is afloat. + afire, awash

Some of the above prefixes have been "absorbed" into words. They are still separate open syllables, but the vowel is "weak" like a short i or u sound. Here are some examples:

retard, retract, prevent, depart, deprive, belong

SUFFIXES

An affix added on the end of a base word is called a suffix. When we add the suffix able to the end of "like," we get "likeable." We might say, "I like Mary. She is likeable."

COMBINING FORMS

Many English words contain roots (stems or bases) borrowed from Greek and Latin words. For example, the word "port" comes from a Latin word, "portare," meaning to carry. The are is a Latin word ending. The root meaning of "import" is to carry in and "export" is to carry out. "Report" is to carry back, particularly a message. A "porter" is one who carries. Here are some more "port" words: seaport, deport, passport, portable, transport.

The present meaning of many words has often changed from the root meaning. Therefore, we will not cover Greek and Latin roots except for a special kind called combining forms. They are often used to build new compound words especially in science and technology. For example, "thermometer" combines therm meaning heat with meter meaning a way of measuring. "Phonograph" combines phon meaning "sound," with graph meaning "to write."

Combining forms are often called affixes, but a combining form can make a word by adding an affix. For example, we can make a word by attaching the suffix ic to graph. A "graphic" is a picture or a writing or drawing. We can't make a new word by joining a suffix to a prefix. We can look up affixes and combining forms in a good dictionary.

A combining form may be attached to another combining form (autograph), to a word (malpractice), to a root (atmosphere), or to an affix (graphic). A vowel is often added to a combining form, e.g., auto or bio.
