 Chicano English, also referred to as Mexican American English, is a variety of North American English predominantly spoken by Mexican Americans or Chicanos in the southwest of the United States. The notion that Chicano English is simply American English influenced by Spanish is widespread, but inaccurate. Chicano English is neither Pigeon nor Spanglish, but rather a fully formed dialect of North American English. As contact and immigration increased between Mexican and American settlers in the 19th century, English became a common, non-native learner language for the Mexican immigrants. Over time, this learner language developed into a consistent dialect that maintained several features of Mexican Spanish phonology, syntax and semantics. Chicano English has many phonological features that demonstrate the Spanish influence. For example, a deprosity is an intermediate between Spanish syllable timing and English stress timing. Furthermore, Chicano English exhibits word final consonants cluster reduction so that mind is pronounced as mine or left as left. Probably, as a result of the influence of non-wattle, advocates such as ch and sh are merged leading to the pronunciation of teacher as teacher and homophones such as chips and chips. Another phonological feature of Chicano English is the absence of dental fricatives, resulting in a pronunciation of think as tink, think or sink.
