Somehow I knew you were going to say that. :) I've also heard this kind of story from quite well-known linguists, but I've never been able to buy into it. For one thing, the fact that they have the same alternation doesn't mean much. You get exactly the same type of alternation with past tense <ed>: walk[t] - beg[d] - load[Id]. This points to a common phonological basis for the alternation, so it is not surprising for homophonous morphemes to undergo the exact same process. Another factor is one that has been discussed many times on this list: the possessive -'s attaches to phrases rather than words. This is not true of the plural or 3rd singular. They have different syntactic distributions. I suppose you know all of this though. Marcus
