WORDS WITH AFFIXES - PREFIXES

2. 49
Dear Learner,
Good day learner? How are you today? In the previous module
you’ve learned about words. In this module you will learn how to
decode words with prefixes.
This module will help you form new words by adding the right or
appropriate prefixes. One way of expanding one’s vocabulary is
through the use of prefixes.
Below are the most common prefixes un-, in-, dis-, im-, and ir-,
and are often used to mean “opposite of” or “not”. Use these prefixes
to complete the thought of the second sentence by supplying the
correct word with the correct prefix. The italicized expressions are
clues.
1. The princess couldn’t decide who to marry.
She’s still __________________________________.
2. The prince was not attentive to the princess.
The prince was ______________________________.
3. The curse was quite not possible to solve.
It seemed ________________________________.
4. The queen did not seem to agree with her daughter’s plan.
She wanted to _____________________ but could not stop her.
5. The prince was not able to satisfy the second witch.

Let’s Study This
It was Benny’s twelfth birthday and the family
was preparing a big celebration for him. While
waiting for the guests to arrive, Benny went to the
park to try out his new bicycle. While there he met
misfortune. Another bicycle bumped him at the rear
and Benny was thrown out of his seat right into the
path of a speeding tricycle. Luckily the park
administrator had taken precautions for such
incidents. An announcement was made through the
microphone and the first-aid attendants came to
take him to the first-aid station. We found him
waiting for us at the anteroom whiling away his time
with the microscope. Benny’s injuries were not
serious and the birthday celebration did not have to
be postponed.

1. Who was celebrating his twelfth birthday?
2. What happened to him when he tried out his new bicycle?
3. How did the park administrator take precautions for such
incidents?
Read the italicized words taken from the paragraph.
bicycle tricycle microphone microscope
misfortune precautions anteroom
• What are placed before each word?
bi, mis, tri, pre, micro, ante
• What does each syllable mean?
• What do you call these syllables
Note further that these syllables come at the beginning of the
base word. You probably know by this time that these syllables are
prefixes. As you can see from the examples given, you can form new
words through the use of prefixes. You can also get the meaning of a
word when you know the meaning of the prefix and the base word is
familiar to you.
The most common prefixes un-, in-, dis-, im-, and ir- are often
used to mean “opposite of” or “not”.
Look at the examples.
impatient discomfort irresponsible unlike

Missing Prefixes
Directions: Read the story. Use the prefixes in the word box to write
the missing prefixes.
As usual, the Little Prince of Mars sat in front of his big-screen
vision. “This life is very interesting,” he thought. Just
then, he heard a knock at the door, a messenger handed him a
gram. “There must be some take,” said the Little Prince. But
when he opened the envelope, he was surprised. The happy
frown on his face appeared. He was going on a trip to the
stars! The Little Prince was certain what to pack. He dashed
for his scope and magic crystal kit. He packed and
packed his star travel bag until everything fit. Someday he would
turn to his own planet, but until then, he was ready for an
adventure in the stars.
