ABSTRACT
This chapter addresses the existence of laryngeal cooccurrence restrictions in eleven languages: Souletin Basque, Sanskrit, Cuzco Quechua, Peruvian Aymara, Ofo, Gojri, Bolivian Aymara, Hausa, Old Georgian, Tzutujil, and Shuswap. The typological statement of laryngeal cooccurrence restrictions is quite restrictive, and shows several striking characteristics. In these languages, all identical elements can cooccur. The incomplete identity effect is manifested in Shuswap and in Ofo. These restrictions result from the constraint rankings that are necessary to generate the similarity-based cooccurrence restrictions. The phenomena of laryngeal cooccurrence restrictions emerge from the interactions of constraints that penalize the cooccurrence of similar segments, a constraint that requires identity, and constraints that enforce the correspondence of laryngeal features between input and output forms.
