A Learner's Polish-English Dictionary contains over 27,000 entries. It is intended primarily for the use of the English-speaking reader of Polish, interested in arriving at the central or commonest meaning of a word, not in an exhaustive set of usages and definitions. It does not attempt to cover technical or scientific terms, or the names of uncommon plants and animals. Most terms related to the social sciences and the humanities are included. It is expected that the user will be familiar with the principles of Polish inflection. Regular and predictable endings and formations are not given. The technical apparatus is kept to a minimum and should be mostly self-evident. Grammatical indicators refer to descriptions in the author's Grammar of Contemporary Polish (Slavica: 2002), to which the user is referred for descriptions of grammatical inflections and usage.
