    Vocabulary : using prefixes

    In test we have seen that suffixes could be very helpful to enrich our vocabulary and make it more varied. The same thing can be found using PREFIXES (placed before the root, or stem, element). We're going to study the right methods to make these new words.                   


    The use of prefixes is precious to "enrich our vocabulary". Indeed, doing some mental gymnastics will enable us to increase our vocabulary dramatically and to say what you mean more easily.

     * To express a negative meaning or indicate that something is badly done= mis / mistake/ misspelt  




     * To give the opposite of what was said before: there are many different prefixes to form the antonyms of given words...  Very often, the prefix depends on the initial syllable of the word. 



                         dis- => disgrace/ dishonest/ disloyal/ disobedient 

                         ir- => irrational

                         ill=> illicit/ illogical/ illegitimate

                         in- => invisible/ inflexible/ independent/ insensitive

                         im-=>impossible/impractical/ immature/ immodest

                         un- => unable/ unfriendly/ unpleasant

                         non- =>nonsense 





    Other frequent prefixes:

     *  peri => perimeter= Around                                                  intra=> intravenous= In, within

     *  -pre/-ante=> antecedent= Before       inter=> international= Between - expresses reciprocity

     *  extra => extraordinary= More                         sub=> submarine= Under, beneath

     *  post=> postpone= After                                                       anti=> antisocial= Against

     *  under/ over=> underweight/ overpopulated= Degree               




    There you are, now! Ready for the test! THE FORCE is with You!
