Are you a writer? Or a word geek? If you write anything or play word games, dictionaries, thesauruses, and other reference tools can come in handy. We’ve found some useful offline and online tools for looking up words, finding synonym, or building words in Scrabble.
Dictionary and thesaurus programs and websites allow us to go beyond the dated, printed dictionary. You can find so much more up-to-date information on the web without having to buy dictionaries and other reference books. The following programs and websites provide useful reference tools for free.
Offline Desktop Software
The following software programs are offline programs you download and install on your computer. Some of the downloads may be large because the programs include the full dictionaries with the program for offline use.
Ultimate Dictionary is a free dictionary program for Windows that is easy to install and use. It contains a collection of around 61 dictionaries, which includes dictionaries, thesauruses, and glossaries, as well as English, Spanish, French, and Polish word references.
When you type a word into the search box Ultimate Dictionary, it looks for it in all the dictionaries it contains at once and provides a meaning from each dictionary in which the word was found in the right pane. The results start to display as you type the word with hints provided for matching words. Quickly jump from one information source to another (translations, encyclopedia entries, glossaries) simply by clicking the Jump to Dictionary button and selecting a reference source from the list on the left.
WordWeb is a free dictionary program for Windows that provides a dictionary and a thesaurus. Each word is accompanied by synonyms, and where available antonyms (a word having a meaning opposite to that of another word), meronyms (a word that names a part of a larger whole; for example, “finger” is a meronym of “hand”), hypernyms (a word that is more generic than a given word; for example, “car” or “airplane” are hypernyms for more precise terms like Toyota Camry or Boeing 747), holonyms (a word that names the whole of which a given word is a part; for example, “hat” is a holonym for “brim” and “crown”).
WordWeb provides a keyboard shortcut that allows you to look up any word anywhere on your computer. By default, the keyboard shortcut is Ctrl + Right Click, but this can be changed in the Preferences. WordWeb also has access to online references that include Wikipedia, Wiktionary, and WordWeb Online, allowing you to access word definitions on the internet.
You can also access a history or your word searches, copy the results of a lookup, and click on any word displayed in WordWeb to display a definition of that word.

Each of these links takes you to a definition and example of the relative category. When you select a relative in Artha, its corresponding definition is scrolled to and highlighted for easy understanding.
