Abstract
In this paper, we use harmony systems with multiple feature spreadings as a litmus test for the possible configurations of items involved in certain dependence. The subregular language classes, and the class of tier-based strictly local (TSL) languages in particular, have shown themselves as a good fit for different aspects of natural language. It is also known that there are some patterns that cannot be captured by a single TSL grammar. However, no proposed limitations exist on tier alphabets of several cooperating TSL grammars. While theoretically possible relations among tier alphabets of several TSL grammars are containment, disjunction and intersection, the latter one appears to be unattested. Apart from presenting the typological overview, we discuss formal reasons that might explain such distribution.
Keywords: mathematical linguistics, phonology, harmony, typology, partitioning
