Merriam-Webster Unabridged Dictionary
Use the world's largest, most comprehensive American English dictionary to find the definitions of words and check your spelling. Look up words by language of origin, date of first use, or part of speech. Find examples of words used in context. The "reverse" dictionary lets you look up words when you remember what a word means, but not the word itself. Merriam-Webster Unabridged is based on Webster's Third New International Dictionary and includes thousands of additional words and supplemental information since the publication of the Third New International.
