ABSTRACT

Consider linguistic difference. 'Vhile pronunCIatIOns vary, grammatical variation is tightly constrained. It is not the case that grammatical differences of the kind that distinguish English from French or Cherokee are rigid. English speakers can invert subject-predicate word orders, for example: "The instructor was driven to drink by the student's passive sentences". In fact, English speakers do sometimes employ case markers, for example, "'s" for possession as in: "the student's passive sentences". 'Ve can produce ergative constructions, replacing "the bottle broke" for "I broke the bottle". Moreover, there are converse orderings of Englishlike constructs in apparently grammatically distinct languages [For discussion see (Pinker and Bloom 1990)J.
