  The upshot of all this is that there is no nontrivial, interesting, "natural", projectible property that all tokens of a word have in common, other than being tokens of that word (in the sense of ‘word’ indicated). Tokens are all the same word, but they are not all the same. That is, the answer to (iii) is no. What then, of the other questions, (i)-(viii)? They become more difficult to answer.  Wetzel (2002) attempts to answer them. The primary conclusion of Wetzel 2002 is that words are theoretical entities, postulated by and justified by linguistic theory. Words, in the sense indicated, are individuated by a number of variables, including orthography, phonology, etymology, grammatical function and sense(s). As for their tokens, they are apt to have some but not all of the properties of the type. And, as the story from Kaplan shows, tokens may even be quite deformed. These considerations impact significantly on the relation between types and their tokens, discussed in the next section, §5.
