The dictionary is a living teacher. Whenever you come across a new word, just consult it and you will get a clear definition. Every student whether attending school or selftaught, should always have a dictionary at hand. As a study aid, it is convenient, inexpensive and almost omniscient.
Skills will develop with your constant use of various dictionaries. The more you use them, the more familiar you will become with them. Sooner or later, you will be quite skilled in finding the page, scanning the entries and locating the exact meaning of the new words. But you should have one thing in mind. As a language student, you can never be come too much attached to dictionaries. Basic language skills do not come from dictionaries, but from your practice. Expose yourself to the language by listening, speaking,reading and writing more, and that is the only way to the mestery of a language.
