This state-of-the-art volume features fourteen contributions by internationally renowned scholars covering three areas of contact linguistics: (1) Creolistics, beginning with an essay on the rise of the meaning and use of the word criollo, followed by studies of linguistic features of African American English, bozal Spanish, and Afrikaans; (2) German language varieties spoken in different periods and regions of the United States; and (3) theoretical issues central to analyzing language contact phenomena. Fittingly, social factors figure prominently in these analyses of language structure, providing a comprehensive view of the issues and topics to which Glenn G. Gilbert has dedicated his professional life.
