Spirits are semi-corporeal beings that exist as souls without discrete bodies. They are distinct from incorporeal undead in that unlike undead, spirits never had a body to begin with and were never “alive” in the corporeal sense. They are often manifestations of a concept, and possess varying levels of powers. The more powerful spirits are often worshipped as gods, especially given that true deities are unlikely to respond to prayers. Spirits, on the other hand, are not nearly as powerful, but the ones inclined to help mortals are often quite happy to do so in their own limited way.
