  • Question 1

Create the antonym of the following word by adding the prefix un-.

 

friendly

CORRECT ANSWER
unfriendly
EDDIE SAYS
Good effort! A prefix is a string of letters that are added to the start of a root word to change the meaning. In this example we need to add the prefix 'un' to the root word 'friendly' to change the meaning to it's opposite meaning. Remember a prefix always go at the beginning of a word.
  • Question 2

Create the antonym of the following word by adding the prefix im-.

 

possible

CORRECT ANSWER
impossible
EDDIE SAYS
Keep it up! We can add the prefix 'im' to the start of 'possible' to create 'impossible'. This is the antonym of 'possible'. Remember antonym's are opposites they have opposing meanings.
  • Question 3

Create the antonym of the following word by adding the prefix ir-.

 

responsible

CORRECT ANSWER
irresponsible
EDDIE SAYS
Great job! The trick here is to remember that a prefix is added to the start of the word. You do not need to replace any letters here, you just add 'ir' to the start of the word to change the meaning. You got this!
  • Question 4

Create the antonym of the following word by adding the prefix in-.

 

capable

CORRECT ANSWER
incapable
EDDIE SAYS
Did you get it? 'Capable' means to have the ability to do something. To create the antonym of 'capable' we just need to add the prefix 'in' to the start of word. This gives us 'incapable' which is when you are unable to do something, it has the opposite meaning.
  • Question 5

Create the antonym of the following word by adding the prefix dis-.

 

appear

CORRECT ANSWER
disappear
EDDIE SAYS
Super effort keep it up! Look at the word 'prefix', 'pre' means before so just keep in mind that a prefix goes at the start of the word to change the meaning. Adding the prefix 'dis' to the root word 'appear' gives us 'disappear'.
  • Question 6

Which of the following words is the antonym of pleased?

 

(Use a dictionary if you are not sure!)

CORRECT ANSWER
displeased
EDDIE SAYS
You can do this! Here we are looking for the word that shows someone is not pleased. Look through the options and say them aloud. Which one sounds correct? To create the antonym for 'pleased', we add the prefix 'dis'. The correct answer is 'displeased'.
  • Question 7

Which of the following words is the antonym of moral?

CORRECT ANSWER
immoral
EDDIE SAYS
The trick here is to remember the rule that any word that begins with an 'm' uses the prefix 'im' to change it's meaning. If your unsure you can always use a dictionary to look up the words to check. Keep up the great effort.
  • Question 8

Which of the following words is the antonym of relevant?

CORRECT ANSWER
irrelevant
EDDIE SAYS
Great to see you having a go! There is a rule we need to remember here. When a word begins with the letter 'r' the prefix 'ir' is added to change the meaning. This give us the correct answer of 'irrelevant', which is the antonym of 'relevant'. Nearly there!
  • Question 9

Which of the following words is the antonym of adequate?

CORRECT ANSWER
inadequate
EDDIE SAYS
Good job! This is a tricky one! You need to find the opposite meaning to 'adequate'. If you are unsure of a meaning you can use a dictionary to find out. Read aloud each option to help identify the correct answer. Sometimes you can tell which is correct just by listening to the way it sounds. The correct answer is 'inadequate'. We add the prefix 'in' to get the antonym we are looking for.
  • Question 10

Which of the following words is the antonym of organised?

CORRECT ANSWER
disorganised
EDDIE SAYS
Super star! The antonym of 'organised' is 'disorganised'. The prefix 'dis' has been added to the start of the root word 'organised' to give us the opposite meaning. Just remember antonyms are opposites and a prefix goes at the start of the word to change the meaning.
