The "Southwest" dialect, previously isolated in San Antonio, Texas, has been isolated south of that area. Data were drawn from the Linguistic Atlas of the Gulf States (LAGS) and interviews with ten lower-middle/upper-lower class informants. Seven communities were represented by seven female and three male English speakers (four monolingual Blacks, three monolingual Caucasians, and three bilingual Caucasians). Eight distinctively "southwest" phonological variables, discussed in previous research on the dialect, were found to exist in the speech of all ten informants. The distinctively Southwest vocabulary (Spanish-English blends) previously noted also exists. It is proposed that the Southwest dialect be considered a Spanish dialect as well as an English dialect. It is noted that while the LAGS field records were not designed to capture bilingual data, its protocols suggest means of analysis. (Author/MSE)
