Discussion of eight major works relevant to a linguistic description of Puerto Rican English seeks to contribute to a more unified theory of bilingualism and second language acquisition. The author's observations on phonological, lexical and morphological, and syntactic implications are presented in an attempt to coordinate the theory. The works, including a general analysis of each, are: (1) "Bilingualism in the Barrio," (2) "The Development of Phonemic Analysis for an Oral English Proficiency Test for Spanish-Speaking School Beginners" (Oral English Language Proficiency Test 1), (3) "A Phonological Study of English as Spoken by Puerto Ricans Contrasted with Puerto Rican Spanish and American English," (4) "The Puerto Rican Study, 1953-1957: A Report on the Education and Adjustment of Puerto Rican Pupils in the Public Schools of the City of New York," (5) "Puerto Rican English Phonotactics," (6) "The Grammatical Structures of English and Spanish," (7) "The Sounds of English and Spanish," and (8) "Spanish Phonology." A summary of general methodological and theoretical points is included. (RL)
