This book aims to provide a better understanding of convergence and non-convergence phenomena
such as divergence from different theoretical perspectives. It brings together nine case
studies that deal with contact between languages found in the Iberian Peninsula (Castilian
Catalan Portuguese and Basque) between Spanish or Portuguese and another language (such as
English) and between different varieties from Europe and other continents. The volume thus
unites views from two fields that rarely interact: contact linguistics and dialectology. It
discusses the mechanisms and consequences of language contact within the Ibero-Romance world a
geographical space characterised by a high rate of multilingual speakers and settings. The
contributions deal with various combinations of convergence and divergence for example between
different varieties of the same language language stability despite contact as well as less
studied aspects such as the relation between language contact and second language acquisition
the linguistic landscape perspective of language contact and divergence in linguistic identity
construction.
