This project came out of the fact that as I began learning the characters I realized that knowing the radicals helped me learn new characters a whole lot faster than just trying to remember each character based on it's own merits, since sound and meaning is typically included in the component choices. What I find is strange is just about all the advice for studying chinese I've read and been given says learning the radicals isn't so important for a beginning student. Possibly because of this view I could find very little material that allows someone to study just the radicals themselves. This is basically a dictionary which covers all the radicals and their variants; several components are also included. The data includes meaning, notes, and etymology. Frequency information is included for the KangXi radicals and their variants (this is RANK, higher means more frequent). There is also a note for each character whether there is any point in learning it as a standalone character. The additional radicals from the modern simplified chinese tables are covered where possible, though in some cases these radicals only exist in extension B. I've now updated this for Pleco 2.0, the updates include: A number of new characters, particularly a number of Extension A characters which had been skipped before. Notes have been expanded to include how the radical is typically used in characters and the types of characters that will be listed under it. A Mnemonic field has been added, in many cases this was just separated from the notes data in the previous release, but this information has been expanded/refined in many cases. While this field is often the technical etymology that can't always be guaranteed. Examples have been added as per a request here, chosen to illustrate the most typical uses of a given radical There is a new 'Distinguish From' field A flashcard list is now included. Feedback is welcome, next steps is to put some effort on the various character components. Sources Primary Sources: Tan Huay Peng's Chinese Radicals These are great little books, highly recommended for this topic. Out of print but can still be found in bookstores. The Chinese Etymology website William Mcnaughton's Reading and Writing Chinese characters The Unihan Database Additional resources include: Unicode Code page reference docs on http://www.unicode.org Modern Chinese Character Frequency List I used the radical tables from the old open source version of Hanzi Master as an original source for the rank calculations, updated for my complete radical list Cantodict This site proved useful for finding the code points of some rare characters In addition to abovementioned sources all of the dictionaries within Pleco were consulted before writing the definition, a couple verbatim copies came from Unihan or CEdict. I also found component information on a number of sites, I think one of the main resources I used was a variant of the Unihan database somewhere on mandarintools.com. Wenlin was consulted for some component information and some of the etymology updates Note: due to some bugs in Pleco's handling of radical characters, the dictionary will not actually be searchable for some radical characters yet - this will be corrected in a future update. iOS Dictionary Installation 1.
