A common need among Algonquian language revitalization programs, especially those with no or few first-language speakers, is novel vocabulary. This paper describes a web-based, open-access comparative database of Algonquian derivational morphemes, now in its pilot phase. We have two main goals: to provide tribes with a source for novel word creation, and to provide a basis for reconstruction of Proto-Algonquian derivational morphology. Derivational morphology in Algonquian languages is famously complex; words are composed of ‘components’, which are divided into categories traditionally called ‘initial’, ‘medial’, and ‘final’ because of their placement relative to one another. The web interface will allow users to view the components along with their reconstructed forms. For language activists, the immediate benefit will be the ability to create neologisms as needed. Additionally, with knowledge of the sound changes their language has undergone, it will be possible to figure out what an unattested component would look like.
