dictionary   There are numerous forms and types of dictionaries, the most familiar being general English language dictionaries such as the American Heritage Dictionary or Webster’s dictionary of the English language, used for guidance on the definition, spelling, pronunciation, and etymology (history) of words. Another very commonly found type of dictionary is a subject dictionary, which is a dictionary devoted to a specialized field, such as Dictionary of Symbols in Western Art, Historical Dictionary of African Americans, and the Dictionary of Botanical Neuroscience.
