Abstract: There are plenty of old sources on the French of the Antilles, but many of them have been neglected. We do know, however, that the simplest of inventories of the language of a Francophone region enriches the general language at the same time. This is the case with the diverse facets of the correspondence of the Bourguignon E. Berthot, a government officer in Guadeloupe in the mid-nineteenth century.
