    Thanks to everybody who replied to what was not as inocuous a question as I thought. I have probably thanked everybody individually, so if your name doesn't appear in the summary it's not through ingratitude. The 'proper' summary should wait till I've digested all the responses and done all the assigned reading, but I may not live that long.

    1. My original wuery was whether there were other pheromena like the English his-genitive (John his book, etc.), where an affix apparently climbed the grammaticalization hierarchy the wrong way and became a word. That is, is grammaticalization (or the mere fact of being 'grammatical') a black hole or a sink in the dynamical systems theory sense. It certainly is the latter in the sense of 'flow lines' converging on it.

    Lots of people questioned my analysis: the mere fact that the his- genitive is later than than the -'s genitive doesn't mean it's a reanalysis of it (the post hoc ergo propter hoc fallacy). This of course is true.

    Also many respondents (especially Hartmut Haberland, Tom Shannon, Martin Haspelmath) pointed out a postposed pronominal possessive in other Gmc languages, e.g. the German meinem Vater sein Haus with dative of the first possessive, Dutch mij vader zijn huis, and the further reduced Afrikaans clitic type my vader se huis. None of these could be from an old affixal form, but are new alternative creations, what Meillet would call 'renouvellement' rather than degrammaticalization. The fact that -'s has the phonological shape it does then may trigger the choice of 'his' as the postposed form; this is also a good story because at this stage his is not only masculine but neuter (its doesn't arise till much later).

    2. As pointed out by Martin Haspelmath and Andrew Carstairs-McCarthy, my analysis of the modern -'s genitive as an affix is faulty: it's now best taken as a clitic. If this is so, then in fact it is itself a better example, since the modern -'s is itself then a clitic that has exited from the affix sink (it's been a suffix as long as anybody knows). In fact the affix-to-clitic move is so well known and patent that I wonder why I didn't think of it. Until well into Middle English times what Jespersen calls the 'group genitive', i.e. '[the king of England]'s' nose did not exist, bu the usual type was '[the king]'s nose of England'. In Old English the usual structure, before the use of the of-possessive would have been 'the king's nose England's'; Jespersen (Modern English Grammar 17.1) cites one that would parse as 'Aethelwulf-gen.sg daughter West-Saxon-gen.pl king- gen.sg.', i.e. in the later form [Aethelwulf King of the West Saxons]'s daughter'.

    It is therefore clear that the modern status of the genitive is the kind of case I was looking for.

    3. Several people (Linda Colemean, Kevin O'Donelly) have pointed out the case of the Modern Irish -muid, which apparently is a verbal concord on its way to becoming a fre pronoun, and a number of Uralic cases appear in Lyle Campbell's paper in the Traugott & Heine 1991 collection. Hartmut Haberland has also suggsted Greek ksana 'again', which derives from a complex verbal prefix.

    4. Somewhat similar phenomena (but in a sense less 'erious') have been suggested by others: e.g. what might be called neoclassical affixoids > words in collocations like 'I'm anti that', 'Your argument is becoming very meta' (Stephen Spackman), or '-ism' as a noun (Robert Beard); and of course there's always 'pros and cons'. Others suggested bus < omnibus as a kind of cross-linguistic example, but this is more in the nature of learned word-play to begin with or deliberate clippling (like mob < mobile vulgus). But this kind of thing (and metanalysis in general) do show an ability and willingness to segment the unsegmentable, and reify the unreifiable. ALso of course pseudo-affixes like -kini (bikini = bi-kini, hence monokini for a topless one), similarly '-tique' = 'shop'.

    5. I was not trying to claim of course that the 'proper' hierarchy is not the commonest direction, and for good reasons. Grammaticalization is a normal attractor, annd like all point attractors it takes a special kick to get something out once it's fallen in. But is not a black hole in the strict sense. What I was interested in is how common the phenomenon of reversal is, and it seems that the answer is as I suspected not very. But it can't be discounted.

    6. As a final pint, along the lines of something brought up by Jason Johnston, how does one treat movement along a sequence where say a thematic noun-class marker that was once (possible) a derivational affix becodmes more 'informative' by turning into an inflection? E.g. the -Vn- formative that occurs in Latin n-stems like homo, hom- in-is is in Latin (whatever it might have been earlier) mainly a declension marker; but in Germanic this thing gets reconstrued as a case/number morph. So in the cognate OE guma 'man', gen/dat/acc sg, nom/acc pl guma-n, what's left of the declension marker has syntactic functions. Is an inflection more 'lexical' than a class-marker? I'd say yes. Of course again the opposite is comoner, e.g. if as is commonly believed the -s- in cleanse (< OE claen-s-ian) is some kind of descendant of the IE -s- aorist marker.

    I have found the whole thing very interesting and informative, and would be delighted by further public or private discussion.

    Thanks again to everybody who replied, and whose replies occupied a rather small amount of disk space in relation to the queries about the 'real story' of the South African election, which occupied more of my time lately than linguistics. What you got on CNN and Sky News is as close as you'll get for the moment.
