Online Webster’s Dictionary: A list of words, with their definitions, or corresponding words in other languages is called a dictionary. Most dictionaries also provide information on pronunciation, grammar, history, and etymology or the origin of the word. They can also have examples of use in sentences. Dictionaries are most commonly available in the form of a book, and the list of words is generally in alphabetical order. The unabridged Webster’s Third New International Dictionary contains almost half a million words, including new words and their meanings, and is quite descriptive in style. It is available in hardcover, with a companion CD, and a free one-year subscription to the website. It describes words using multiple contexts and in short sentences, which explain the meaning as used in various forms. The online Webster’s dictionary has all these features. It also contains articles and news that are related to language and word usage, an online store, and a special resource for spelling bees. Moreover, the online Webster’s dictionary site has a daily crossword, word puzzles and word games, daily buzzwords for kids, learner's word of the day, a daily podcast, along with an online word search that is free, and thesaurus lookup. This site is owned by the reputed publishing house, Merriam-Webster, which continues a tradition that began with the first American dictionary, compiled by Noah Webster, called A Compendious Dictionary of the English Language, published in 1806.
