As the first major survey of relative clause structure in the indigenous languages of Mesoamerica, this volume comprises a collection of original, in-depth studies of relative constructions in representative languages from across Mexico and Central America, based on empirical data collected by the authors themselves. The studies not only reveal the complex and fascinating nature of relative clauses in the languages in question, but they also shed invaluable light on how Mesoamerica came to be one of the richest and most diverse linguistic areas on our planet.
