More than a simple online dictionary, the Oxford Dictionaries website includes a number of features that will appeal to writers, writing instructors, and word-lovers of all sorts. For one, this is a "living dictionary," providing helpful information about the origins of words and noting how the colloquial uses of certain words have shifted over time. For example, the entry for nonplussed notes that although the word means confused, it has developed an informal North American definition as "not disconcerted; unperturbed." The Dictionary feature also provides numerous example sentences and possible synonyms. Collectively, these features enable one to not only look up words, but to also evaluate the most appropriate words to use for a variety of writing tasks. In addition to the extensive Dictionary feature, the Oxford Dictionaries include an extensive grammar guide that provides detailed and accessible explanations of verb tenses, punctuation, and a helpful list of commonly misused words and writing mistakes. Finally, Oxford Dictionaries also features a delightful Explore section, where readers will find answers to common queries about words and language.
