Last speaker of the Cornish language
Open-knowledge reference entry
Identifying the last native speaker of the Cornish language was a subject of academic interest in the 18th and 19th centuries, and continues to be a subject of interest today. The traditional view that Dolly Pentreath (1692–1777) was the last native speaker of the language has been challenged by records of other candidates for the last native speaker, and additionally there are records of others who had knowledge of the language at a later date, while not being native speakers.
Finding the last speaker of the language is complicated by the lack of audio recordings or transcriptions owing to the date of the language extinction. It is very difficult to know, without such evidence, whether those reported as speaking Cornish into the 19th century were able to speak the language fluently, or even whether they were speaking it at all. A substratum of Cornish vocabulary persisted in Cornish English, and in some cases those identified as Cornish speakers may have been speaking English with heavy Cornish influence.
Nevertheless, the difficulty of identifying the last speaker has not prevented academics spending considerable effort on the topic.
History
It will probably be impossible to establish who the definitive "last native speaker" of Cornish was owing to the lack of extensive research done at the time and the obvious impossibility of finding audio recordings dating from the era. There is also difficulty with what exactly is meant by "last native speaker", as this has been interpreted in differing ways. Some scholars prefer to use terms such as "last monoglot speaker", to refer to a person whose only language was Cornish, "last native speaker", to refer to a person who may have been bilingual in both English and Cornish and furthermore, "last person with traditional knowledge", that is to say someone who had some knowledge of Cornish that had been handed down, but who had not studied the language per se.
The last known monoglot Cornish speaker is believed to have been Chesten Marchant, who died in 1676 at Gwithian.

Why this record matters
The phrase “open-knowledge reference entry” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 26, 2026. The linked authority identifier is Q6494910. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1692, 1777 and 1676.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
