I pull back at the diminutive. It works through and with ideas like reference, then moves into the whole problem of how meaning is constructed, how Signification works. Or, how Signification plays, and makes serious fun. When the same word points to many things or in this case persons, the word calls attention to itself and to how it goes about its work of making meaning. But multiple names alone don't make Signification a big enough problem.
More complex things do that work.
Professor Davenport's Life of the Irish Saint Brendan works very hard to complicate the whole idea in a way similar to how Arthur's epitaph works. First, the meta-statement. In other words, in Ancestors Maybe, which takes place in Middletown, Connecticut, there is no there there. 1 city cen Conn. S of Hartford pop 39,040. By asserting that Middletown does not exist, MacKiernan severs the relation between Middletown, the signifier, or word, and the referent Middletown whose statistics Webster's gives you in its gazetteer.
