LogFreq(Zipf) refers to the Zipf value of the word (Spelling). The Zipf value ranges between 1 to 7 (Zipf value 1-3: low-frequency words; 4-7: high-frequency words). Information about Zipf values, the database, as well as the columns in the database can be found in van Heuven et al. (2014).

Please note that the column wlen indicating the length of the words (Spelling) was added to the database used on this web page.
