T.: At today’s lesson we are going to learn about prefixes. Systematizing material we’re doing a lot of different tasks.
Firstly, let’s learn what a prefix is.
A prefix is a set of letters that is added to the beginning of a word to change its meaning. Each prefix has a general meaning.
T.: So you will be able to understand what a word with a prefix means more easily.
Let's look at an example.
friendly unfriendly
.: The first man looks very friendly! I think it would be nice to spend time with him.
The second man looks unfriendly. I don't think it would be much fun to spend time with him!
We can see in the second sentence that we added the prefix "un-" to the word "friendly." This prefix "un-" means "not" or "the opposite of."
Here are more examples with the prefix "un-":
happy ----> unhappy
finished ----> unfinished
believable ----> unbelievable
acceptable ----> unacceptable
These words are all adjectives. We can also use the prefix "un-" with verbs.
Look at these examples:
do ----> undo plug in ----> unplug
T.: When you see a word that begins with the prefix "un-", you can know its meaning by looking at the word's root (the part that is not the prefix or the suffix). It might be a word you already know! But, be careful! Be sure you've seen the whole prefix before you decide the word's meaning.
Look at the word below:
underdeveloped
T.: Let's try to find the prefix. Is it "un-" as in underdeveloped? No, that doesn't sound right!
We know the word "develop," which means "to grow bigger or become more advanced." This is the root of our word!
T.: So, the prefix must be under, which means "below," "lower," or "not enough." The word underdeveloped means "not developed enough."
T.: Let’s look at common prefixes, their meaning, and an example word.
Prefix Meaning Example word
dis- not, opposite of disagree
in-, im- not incorrect, impossible
mis- incorrectly misunderstand
re- again redo (do again)
un- not uninteresting
under- below, lower, not enough underwater
