The closely related Lenape ("Delaware") languages Munsee and Unami form a subgroup, with the two languages descending from an immediate ancestor called Common Delaware (CD). Goddard notes a small number of innovations in morphology and phonology that set Munsee and Unami off from their neighbours. As well, similarities between the Delaware languages and Mahican have been recognized in that Mahican shares innovations with Munsee and Unami, suggesting a subgroup containing Common Delaware and Mahican; this group has been referred to as "Delawaran."
