This dictionary is a lexical base for mastering the basics of a foreign language; it can be both a methodological guide and a practical guide to learning foreign languages. The dictionary contains only the most common words that a student of a foreign language must learn in the first place both in order to learn to speak and in order to learn to read in a foreign language. In addition, as conceived by the compilers of this dictionary, it can serve as a dictionary basis for compiling textbooks on foreign languages. The proposed lexical minimum is composed for three languages: English, German, and French. Unlike any, even the smallest pocket dictionary, usually containing about 10,000 words, the lexical minimum consists of only about 3,000 of the most common words and phraseological combinations for each language. They should be learned by everyone who wants to learn a foreign language in the volume of a high school course.
