A thesaurus is a great help if you want to increase your vocabulary. Whereas a dictionary gives you a definition and the pronunciation of a word, a thesaurus lists synonyms (a word or phrase which has the same or similar meaning as another word or phrase) and also sometimes antonyms (a word or phrase which has the opposite meaning of another word or phrase) of it.
The word ‘thesaurus’ comes from Latin and Ancient Greek, and means a collection of important or valuable things. The most well known modern thesaurus is ‘Roget’s Thesaurus of English Words and Phrases’ which the British Dr. Peter Mark Roget began work on in 1805, publishing it in 1852; it has not been out of print since. However, there are other examples even dating back to around 100AD – the Greek author Philo of Byblos wrote a dictionary of synonyms around this time.
It took Roget almost fifty years to single-handedly complete his thesaurus, although he did not devote himself entirely to it until he had retired from medicine in 1840. Even so, it was a huge achievement for one person. In comparison Samuel Johnson devoted nine years of his life to compiling the first English language dictionary and he had six assistants (all crammed into his attic, by the way).
The University of Glasgow’s English Language Department has spent more than forty years producing the ‘Historical Thesaurus of English’ (HTE). As its name suggests, this latest thesaurus does not just list synonyms, but groups words in chronological order beginning with the oldest from Old English up until the newest words of 2003; in total it covers more than 920,000 words. It is claimed to be the largest ever thesaurus and the first historical one in any language. You can find where a word came from and how it evolved over time. You can also search for words which were used during a particular period of time enabling you to find all the words Shakespeare had available to him meaning ‘happiness’, for instance. No wonder it took such a large team of people so many decades to complete it and from such humble beginnings (they started by writing words on individual slips of paper).
While for most of us the HTE will be too expensive (around £250) and even too cumbersome to have our own copy when it is published in October, the good news is it will be available online in the future, linked to the online version of the Oxford English Dictionary.
