800,000 words in online thesaurus

About 800,000 words and more than 1,000 years of the English language have been published in a vast new online database.

The Historical Thesaurus of English is said to be the only resource to make the meaning of every English word from the last millennium available to the public online.

It is a digital version of the Historical Thesaurus of English Project, the printed version of which was first published in 2009 after 44 years of work by academics at the University of Glasgow.
