Window controls

  • images/btn_clipadd.png - Inserts character at the end of the clipboard.
  • Set as learned - Toggles the status of the character between "learned" and "unlearned." Learned characters are displayed in blue in the character list.

The smaller box to the right of the box containing the selected character shows its radical. You can determine which kind of radical is displayed here in the character list settings. If the character has a simplified variant, it is displayed in a second box to the right of the radical. If the selected character is a simplified character, this second box displays the corresponding traditional character.

The lower part of the window displays other kinds of information (including frequency rankings, stroke counts, index numbers, alternate radicals, and encodings). You can customize which details are displayed in character details settings. The types of detailed information which can be displayed here are described below.

Japanese readings can be displayed in kana or in romaji. Chinese readings can be displayed in PinYin/Wade-Giles/Yale or in bopomofo. You can make these choices in romanization settings.

The System of Kanji Indexing by Patterns (SKIP) is a scheme for the classification and rapid retrieval of Chinese characters on the basis of geometrical patterns. Developed by Jack Halpern, it first appeared in the New Japanese-English Character Dictionary (Kenkyusha, Tokyo 1990; NTC, Chicago 1993), and is being used in a series of dictionaries and learning tools called KIT (Kanji Integrated Tools). SKIP is protected by copyright, copyleft and patent laws.

Commercial usage of SKIP in any form is strictly forbidden without the written permission of Jack Halpern, the copyright holder (

Details of SKIP usage can be found in KANJIDIC documentation on this page:
