Cambridge Handbook of Language Contact, Vol 1
by
S. S. Mufwene, A. M. Escobar, eds.
Language contact - the linguistic and social outcomes of two or more languages coming into contact with each other - has been pervasive in human history. However, where histories of language contact are comparable, experiences of migrant populations have been only similar, not identical. Given this, how does language contact work? With contributions from an international team of scholars, this Handbook - the first in a two-volume set - delves into this question from multiple perspectives and provides state-of-the-art research on population movement and language contact and change.
These are just a few examples of books devoted to Linguistics topics, search Tripod for more books and ebooks.
