C One of the quickest and most effective ways to improve your vocabulary is by learning to recognize the most common Latin and Greek roots, since any one of them can help you define a number of English words. Whenever you come upon an unfamiliar word, first check to see if it has a recognizable root. If you know that the Latin root "ami" for example, means like or love, you can easily figure out that "amiable" means pleasant, friendly and "amorous" means loving.
