Historical Thesaurus of the OED

Online Products & Publishing







'The OED gave us individual trees, but never a sight
of the whole forest or helpful pathways through it.
The thesaurus does precisely that.'
David Crystal

The Historical Thesaurus of the Oxford English Dictionary is the largest thesaurus in the world.

Based on the OED, the Historical Thesaurus of the OED (HTOED) contains almost every word in English from Old English to the present, allowing users to explore words connected in meaning throughout the history of the language.

It provides a unique resource for scholars researching linguistic and literary history, the history of the language, social history, and more, and is a perfect complement to the OED itself, allowing the words in the OED to be cross-referenced and viewed in wholly new ways.

'Forty-five years of exacting scholarship by a well-led team have had a triumphal outcome. This book is a magnificent achievement of quite extraordinary value. It is perhaps the single most significant tool ever devised for investigating semantic, social, and intellectual history.'
Randolph Quirk
