This is the first published dictionary of the Nuuchahnulth language of Vancouver Island, based primarily upon the Tsishaath variety and supplemented by material from a number of other dialects of the language. Nuuchahnulth is the preferred term for a group of First Nations peoples occupying the West Coast of Vancouver Island from Port Renfrew to Cape Cook.

This dictionary is a first attempt at providing a detailed account of the lexicon of the Nuuchahnulth language, complete with examples and grammatical information. Prior to this there have been a number of short wordlists (e.g glossaries (e.g. Knipe 1868, Sapir & Swadesh 1939), but there has been no full dictionary with detailed grammatical information and examples published.
