Ubuntu has built-in dictionary software that you can use to look words up. But you must be connected to internet in order to use this dictionary. But if you are online, then there are a lot of online dictionaries available on the internet. So sometimes, working offline, you might need to look up some words. In that case, you need an offline dictionary. Artha is an offline dictionary that you can install in your Ubuntu Box to work seamlessly without the need of being connected to internet.

Artha

Artha is a wordnet based offline dictionary. According to the official website, "Artha is a free cross-platform English thesaurus that works completely off-line and is based on WordNet. Stable releases for download are currently available for GNU/Linux, Microsoft Windows and Windows Phone 7" and "Artha is released under the GNU General Public License version 2; hence you are free to copy/redistribute it."
You can use hotkey 'ctrl+alt+w' to look up a word in Artha or to launch it. To look-up a word in Artha, just select the word and press the hotkey. This hotkey is configurable, i.e. you can use your own keyboard combination to use Artha.

Artha features

Wordnet - Artha uses the cognitive and excellent wordnet Database.

Hot key Lookup - It pops up the meaning of the selected word when pre-set hot key combination is pressed.

Regular Expression support - Regular expressions such as wild cards, joker, character class, and limits can be used to look-up the items in the thesaurus.

Notifications - The balloon tips or passive notifications can be enabled in Artha. In this mode, no new window is popped up, and the work can be continued uninterrupted.

Suggestions - For the words that do not correctly match, it shows near-matched word suggestions.

Senses - Words can have more than one sense in different contexts. From the official website: "You might not know to which sense/definition of a word does a relative map to. In Artha, when you select a relative, its corresponding definition is scrolled to and highlighted for easy comprehension."
"For a given word, the possible relatives shown by Artha includes Synonyms, Antonyms, Derivatives, Pertainyms (Related Noun/Verb), Attributes, Similar Terms, Domain Terms, Entails (what verb entails doing), Causes (what a verb causes to), Hypernyms (is a kind of), Hyponyms (kinds), Holonyms (is a part of) and Meronyms (parts)."
