Help with the component builder
For detailed instructions, see the Component builder how to guide.
To find any kanji, first try to identify the components it is made up of.
For any components you recognize, if you know the English meaning or name, start typing it in the text area. Full details of all components and their English names can be found here.
Alternatively, count the strokes of the component, and scan the list to find it visually.
Example
To find the kanji 漢:
  • Notice that it is made of several components: 氵 艹 口 夫.
  • 氵 艹 口 all have three strokes, so you could look in the list in the 3 stroke section. 夫 has four strokes.
  • Alternatively, you could start typing 'water' (氵), 'grass' (艹), 'mouth' (口) or 'husband' (夫) in the search area, and the components will be highlighted in yellow.
  • Keep adding components until you can see your kanji in the list of matches that appears near the top.
