Strachey’s material was collected sometime between 1610 and 1611, and probably written up from his notes in 1612 and 1613, after he had returned to England. It was never published in his lifetime, although he made a second copy in 1618. The second copy was published in 1849, and the first in 1955. Smith’s material was collected between 1607 and 1609 and published in 1612 and again in 1624. There is no indication of the location where he collected his material. In 1975, Frank Siebert, a linguist specializing in Algonquian languages, published a book-length study claiming the "reconstitution" of the phonology of the language.
Siebert's 1975 study also examined evidence for dialect variation. He found insufficient justification for assigning any apparent dialects to particular areas. Strachey’s material reflects considerable lexical variation and minor phonological variation, suggesting the existence of dialect differentiation. A speculative connection to the Chickahominy and Pamunkey Virginia Algonquian tribes has been suggested, but there is no evidence to support this link.
The table below gives a sample of words reflecting lexical variation. Each word is given as written by Smith or Strachey, followed by a proposed phonemic representation.
For the film The New World (2005), which tells the story of the English colonization of Virginia and encounter with the Powhatan, Blair Rudes made a tentative reconstruction of the language "as it might have been." A specialist in the American Indian languages of North Carolina and Virginia, he used the Strachey and Smith wordlists, as well as the vocabularies and grammars of other Algonquian languages and the sound correspondences that appear to obtain between them and Powhatan.
