A surprisingly large number of conjunctions that correspond semantically to English ‘and’ can be posited for POc, including at least *ka, *ma, *mai, and *mana. It is not clear that all of these are valid reconstructions rather than products of convergence, and if they are assigned to POc the syntactic differences that distinguished their coordinating functions remain unclear. This comparison is attested to date only from the western Solomons to southern Vanuatu, but this is a distribution that is commonly accepted for forms assigned to POc.
