Abstract: Formal mereologies are axiomatised in a variety of different ways, with a variety of different primitives. This paper distinguishes three such ways, whose primitives are part, overlap, and proper part respectively. Not every formal mereology can be axiomatised in each of these ways. This paper considers what formal features a mereology much have in order to be successfully axiomatisable in each way.
