y modeled on the Kimmo treatment of harmony processes and other long-distance dependencies in natural languages". [Barton86, p56] We suggest that words of natural languages are easy to analyze because morphological grammars are small. As Barton shows, two-level complexity grows rapidly with the number of harmony processes. But, fortunately, natural languages don't have very many harmony processes. Any single language seems to have at most two harmony processes: • zero (most, ie. some 88 % of languages), • one (Uralic, Tungusic, Sahaptian) or • two (most Altaic languages) Even in principle, a three dimensional vowel harmony is rather improbable, because it would lead to a total (or almost total) collapse of distinctions between vowels. In most languages there are not enough distinctiv...
