Vocabulary knowledge is knowledge; the knowledge of a word not only implies a definition, but also implies how that word fits into the world. Vocabulary knowledge is not something that can ever be fully mastered; it is something that expands and deepens over the course of a lifetime. What could be better than learning new words daily and drastically enhancing your vocabulary! You would also be able to learn a new "Quote" everyday that you could use for better knowledge in this horizon of English language.
