The English spoken by Spanish-surnamed Americans of the southwestern United States often has a Spanish flavor, even though the speakers may have no competence in Spanish. This Chicano English is discussed in a series of descriptions based on a number of previous studies of regional variations. Each description covers pronunciation, intonation, stress, vocabulary, and syntax. Regions covered include California (East Los Angeles, Riverside and vicinity, Redwood City, Los Angeles, Long Beach, and Whittier), Arizona, New Mexico (Las Vegas), and Texas (San Antonio in the 1950's and in 1970, Fort Worth-Dallas, and Austin). From the evidence of the individual descriptions, certain general conclusions are drawn about the linguistic feature of Chicano English, and especially about its dependence on Spanish influence. Pedagogical implications of this Spanish background are briefly discussed. A partially annotated bibliography is appended. (JB)
