how to improve my communication language?

may i ask what year are you in? first, you have to review your English subjects in elementary & high school. familiar yourself with the rules & exception to the rules of correct English grammar. the correct spelling of a word. since you're in college, try to use words that are more appropriate to your level. avoid using very elementary words when you are already a college student. too embarrassing. as we age, we should enhance our communication skills. how will you be accepted in a company if you have poor communication skills? try also the tongue-twisting words. familiarize yourself with correct usage of past tense, present tense, future tense, past participle etc. plus the adjectives, adverb, noun, pronoun, verb, predicate, plural, singular, linking verbs. also, if you have a close sibling, parent or trusted friend, try to request either one of them to communiicate with you in English. if you're shy, then request them you do it when only the 2 of you are alone in a room. let's say in a classroom or in your home. how's that? i hope it helped you. good luck.

dont get so upset, for good communication one needs good vocabulary, and it can be improved by reading english dailies and watching english news channels like BBC,CNN etc. u can do one thing try to read out loud in front of mirror it will help u be more confident....
