Five papers on bilingualism are presented. "Giving Transfer a Boost--Describing Transfer Variation in Learners' Interlanguage Performance" by Claus Faerch suggests, outlines, and illustrates a heuristic principle for describing the result of positive transfer from one language to another, based on the assumption that learners maximize transfer in both learning and communication. In "Semantic Over-Extension and Lexical Over-Use in Immigrant Swedish" by Ulla-Britt Kotsinas, examples are given of these phenomena in a variety of grammatical situations. "The Relation Between Code Differentiation and Language Mixing in Bilingual Three-to Four-Year-Old Children" by Lenore Arnberg and Peter W. Arnberg, reports a study whose results support a one-system theory of bilingual language acquisition. "The Problem of Divergence in Translation--A Model for Disambiguation" by Jennifer Draskau outlines and discusses a procedure for translators to use to handle problems occurring when one word in the language to be translated can be used in more than one sense in the target language. In "The Reception of English Loans in Sweden" by Magnus Ljung, ten types of English loans are discussed and ranked, the influence of social factors in loaning is examined, age is proposed as the most important determinant of loan use, and some regional differences are illustrated.
