The series Frequency Dictionaries aims at producing dictionaries with comparable frequency data for a large number of different languages. For many of the languages featured in this collection, this series is the first comprehensive compilation using a large-scale empirical base. The dictionaries are available in print and electronic version. Each dictionary provides the most frequent 1000 word forms ordered by frequency and the most frequent 10000 word forms in alphabetical order. They provide an introductory description of the data and the methodological approach. In addition, language specific statistical information on letters, word structure and structural changes depending on word frequency is provided. The enclosed CD-ROM contains a more comprehensive version of the dictionary as an e-book, with data on relative frequency of up to 1000000 word forms given in alphabetical order. This series of dictionaries provides the opportunity to explore comparative linguistic topics as well as monolingual issues such as studies on word formation and frequency-based examinations of lexical areas for dictionaries or language teaching.
