    In his recent posting on "velar softenings as allophonic variation", Andy Spencer observes

    K > CH type softenings are extremely common historically and abound in synchronic morphophonological systems. However, it's extremely hard to track down this type of process as a genuine postlexical allophonic rule (akin to aspiration in English).

    and asks

    (i) Do we really want a phonological theory (e.g. a theory of feature geometry) in which K > CH comes out as a natural assimilation of any kind?

    (ii) Do we really want to analyse K > CH alternations as *any* type of (purely) phonological change?

    (iii) What is the phonetic chain of events that leads to a generation of language learners reinterpreting secondary palatalization of velars as a K > CH alternation?

    (iv) Do these types of phenomena imply that morphophonemic processes (complete with morpholexical conditioning and exceptions) can sometimes arise in a language in a more or less discontinuous fashion, without being the result of gradual lexicalization of purely phonetic or phonological alternations?

    It seems plain to me that the K > CH historical change (including even [k] > [s] developments and alternation) is "natural", insofar as it marks the start- and end-points of a CHAIN of natural phonetic/phonological changes:

    a) presumably the "front velar" [k,] articulation of /k/ before or after /i/ or /j/ is phonetically natural, and easily expressed in various versions of phonological feature theory.

    b) [k,] and [c] would both be plausible, "natural" allophones of /k/ before or after /i/ or /j/.

    c) Before /i/ or /j/, it is not surprising for the aspiration phase of [k,] or [c] to have an [i]-like quality. The distinction between an [i]-coloured aspiration portion and a voiceless palatal fricative [C] (IPA c-cedilla) is largely a matter of duration and air pressure. Otherwise, they are acoustically practically identical. So it is phonetically natural for an aspirated [k,] or [c] allophone of /k/ to come to be perceived and pronounced as a voiceless palatal affricate [cC]. (Jakobson, Fant and Halle analyzed affricates as "strident stops". This is a good example of what they meant.)

    d) Each of the subsequent developments from [cC] through [tC], [tS], and, who knows, [ts], [s] seems, considered step-by-step, both phonetically "natural" (as a historical development), and appropriately represented in terms of a succession of changes to the values of single features. (Or, alternatively, as the privative accumulation of features, an analysis I have set out in a forthcoming paper.)

    If this hypothesis about the historically development of K > CH is more or less correct (it seems pretty uncontentious to me), then since each step along the way is a phonologically natural assimilation, phonological theory cannot help but characterize K > CH as a natural assimilation. It is not as simple an assimilation as T > CH, perhaps, but that might enable us to show why K > CH is rare postlexically. It may not be NECESSARY to treat K > CH as a phonologically natural assimilation, but if we don't make use of the phonological machinery available, one might ask, "why not?". It would seem to be the simplest analysis.

    My responses to Andy's 4 questions, then, are a conservative i) yes, ii) yes, iii) see above, iv) not so far.
