 Peirce believed that the three elements, and the respective classifications they imposed upon signs, could be combined to give a complete list of sign types. That is, since a sign has a sign-vehicle it can be classified as either a qualisign, a sinsign, or legisign. Additionally, since that sign has an object it can be classified as either an icon, an index, or a symbol. And finally, since that sign will also determine an interpretant it can be classified as either a rheme, a dicent, or a delome. Each sign is then classifiable as some combination of each of its three elements, that is, as either one of the three types of sign-vehicle, plus one of the three types of object, plus one of the three types of interpretant. Initially, this seems to yield twenty-seven possible classificatory combinations, but, because of certain of Peirce’s phenomenological theories, there are restrictions on how we can combine the different elements that mean there are, in fact, only ten types of sign. (For more on the relation between Peirce’s phenomenological categories, and his sign typology, see Lizska 1996, Farias and Queiroz 2014, and Savan 1988.)
