Back to basics means making sure you have a good foundation. Many non-native speakers can communicate more or less in English but fall short of their potential. For example, when reading an article, they miss part or even most of the meaning because of certain vocabulary words or expressions they do not understand. Vocabulary means knowing both small and large words. Knowing them means you can spell the word, pronounce word, and use it in a sentence correctly. If you cannot do this, you don't truly know the word. Try reading a child's book written in English. Unless you know every word, your knowledge remains less than that of a child born in the U.S. Small words like in, of, at, on, etc., are used in specific ways, as even young children master them by the time they enter school. Vocabulary is one basic that merits attention. Other basics to consider are grammar, study skills, reading comprehension, error correction, and writing. More on those to come!
