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 MAIN PREFIXES:

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!
