     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

                                                                            

                                            

  T.:  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
