JustTheWord is a completely new kind of aid to help you with writing English and choosing just the word. If English is your first language, JustTheWord can help you express that elusive idea with le mot juste. If you're learning English, JustTheWord can justify your choice of words or suggest improvements - and JustTheWord knows about some common errors made by speakers of your mother tongue. When we write, we search our knowledge of words in two ways. We choose between words that mean similar things. A thesaurus gives us access to this sort of knowledge. But our choice constrains and is constrained by the other words in the sentence. We know, or need to know, which word combinations sound natural. A dictionary gives us access to some of this sort of knowledge. Based on the latest advances in statistical linguistics, and exploiting Sharp's patented analysis technology, JustTheWord combines the advantages of thesaurus and dictionary, and enhances the usefulness of both. By analysing a huge amount of English text, we've built up a highly detailed knowledge base of the word combinations whose mastery is at the heart of fluent English.
