The early loss could thus be reinforced by dissimilation
of *v away from another glide in the following syllable.
Nevertheless, we would like to bring to attention two remarkable details: first, in random trochees the dissimilation
of heavy syllables in odd positions can already be noticed, although it is not so clear as the dissimilation
Moreover, in Saami yet a third example of the same dissimilation
has been discovered: SaaN coska 'block of wood '< *cucki < *cucki, cognate with MdE cocko 'timber, log '(Luobbal Sammol Sammol Ante (Aikio) 2013 : 164-165).
In (16b), however, where the root begins with the voiceless obstruent /s/, these prefixes undergo voicing dissimilation
to gu-, du- and -da-, respectively.
Its chapter on consonants, 55 pages long ("Der Konsonantismus"), included references to Luick's paper on palatalisation of 1935 and to the relevant sections of the Grammatik (363), h-spellings (364), dissimilations
(375), and the change [n > m] in loanwords from French (413).
The correspondence between the Saami and Mordvin initial affricates is not regular, but the Saami representation can be quite naturally explained as due to a dissimilation
of two identical affricates: PU *cucki >> Pre-PSaa *cucki.
Muller-Kessler appears to be unfamiliar with the precise meaning of the linguistic terms assimilation and dissimilation
, since elsewhere she describes the form [?
It is common, for example, for one of the two copies in morphological reduplication to undergo dissimilation
16) The Northumbrian metathesis or anaptyxis affecting /Vrxt/ can thus be explained as a process akin to dissimilation
, eliminating a phonetically difficult cluster.
Another potential explanation is the dissimilation
of /a > u/, attested in Amorite.
In case of dissimilation
a voiced geminate in the weak grade alternates with a combination of a voiced consonant and a stop in the strong grade.
The relationship between grammaticalization and degrammaticalization in this respect may be viewed as parallel to that between assimilation and dissimilation
in sound change.
