WordNet

WordNet is a free open lexical database for English, by Cognitive Science Laboratory of Princeton University under the direction of psychology professor George A. Miller. It is what its name says. Each word will have one or more definitions (or senses, technically). Apart from these definitions, a word is interlinked to other words by a relation like Synonyms, Hypernyms, etc. Generally, We tend to forget a word by learning a word's definitions alone. That's the prime reason, WordNet has this relatives feature by creating a net of words. When you learn a word, you also learn (or would at least glance) its relatives like what are its similar terms, what does a verb entail doing, etc. which makes a complete net of a word and its associates. These are displayed in an easily comprehend-able fashion by Artha.

Senses

A sense is a meaning/definition that a word conveys in a given context and Part of Speech (PoS). Many a time, a word will have more then one sense. The number of senses a word has (polysemy count), determines its familiarity.

E.g. clear conveys a variety of meanings in different parts of speech. Below listed are a few:

As a verb:

   * rid of obstructions
   * make a way or path by removing objects
   * grant authorization or clearance for

As an adjective:

   * readily apparent to the mind
   * free from confusion or doubt
   * affording free passage and view

As a noun:

   * the state of being free of suspicion (the state of being free of suspicion)

As an adverb:

   * completely (slept clear through the night)
   * in an easily predictable manner (she cried loud and clear)

E.g. pass is synonymous to clear with respect to its context "grant authorization or clearance for". (refer third verb sense above)

Antonyms

(Opposite) Words that expresses a meaning opposed to the meaning of the given word, in a given context. Antonyms can be direct, inferred or indirect.

E.g. poor is a direct antonym of rich, while broke, penniless, skint, etc. are inferred antonyms from the direct antonym poor. rich has a sense meaning having an abundant supply of, which makes abundant as a synonym of rich and its antonym scarce, becomes an indirect antonym to rich.
