<!doctype html public «-//w3c//dtd html 4.0 transitional//en»> http-equiv=content-type> On the basis of a world-wide convenience sample of 116 languages, the distribution of zero-marking of spatial relations over the languages of the world is shown to largely escape any genetically, areally and/or typologically based constraints. The main goal of this book is to firmly establish the cross-linguistic occurrence of the zero-marking of spatial relations and to provide a framework for its study in terms of economy and predictability.
