The thesaurus is another useful component of the application. For many entries it provides synonyms, and in some cases examples, to the word that is searched. Having a Thesaurus does not just offer a set of alternative words to an individual but can can also be a valuable aid by helping reinforce and stabilising the understanding of the original word. This provides confidence and growth to the user as well as a reassurance that they can use language correctly.

One example of this is if an individual is unsure about the meaning of the original word, being presented with the thesaurus helps to reinforce the meaning of that word, as well as learn alternatives within the correct context. From user feedback, this has proven to be valuable and in particular to those learning English and as a second language.

The Thesaurus helps the individual to get a better grip of a word as well as sometimes providing a better option than what was first used.
